".SH NAME\r\n"
"Starts a loop based on 'for' syntax.\r\n"

" \r\n"
"FOR %indexvar IN set\r\n"
" command [arguments]\r\n"
" [command [arguments]]\r\n"
" ...\r\n"
"ENDFOR\r\n"

".SH OPTIONS\r\n"
" \r\n"
" %indexvar - Variable name used to index a set\r\n"
" set - Set to be searched\r\n"
" command [arguments] - Command to be executed with optional arguments\r\n"
".SH DESCRIPTION\r\n"
" \r\n"
"NOTES:\r\n"
" 1. The FOR command executes one or more commands for each item in a set of\r\n"
" items. The set may be text strings or filenames or a mixture of both,\r\n"
" separated by spaces (if not in a quotation).\r\n"
" 2. If the length of an element in the set is between 0 and 256, and if the\r\n"
" string contains wildcards, the string will be treated as a file name\r\n"
" containing wildcards, and be expanded before command is executed.\r\n"
" 3. If after expansion no such files are found, the literal string itself is\r\n"
" kept. %indexvar is any alphabet character from 'a' to 'z' or 'A' to 'Z',\r\n"
" and they are case sensitive. It should not be a digit (0-9) because\r\n"
" %digit will be interpreted as a positional argument on the command line\r\n"
" that launches the script. The namespace for index variables is separate\r\n"
" from that for environment variables, so if %indexvar has the same name as\r\n"
" an existing environment variable, the environment variable will remain\r\n"
" unchanged by the FOR loop.\r\n"
" 4. Each command is executed once for each item in the set, with any\r\n"
" occurrence of %indexvar in the command replacing with the current item.\r\n"
" In the second format of FOR ... ENDFOR statement, %indexvar will be\r\n"
" assigned a value from start to end with an interval of step. Start and\r\n"
" end can be any integer whose length is less than 7 digits excluding sign,\r\n"
" and it can also applied to step with one exception of zero. Step is\r\n"
" optional, if step is not specified it will be automatically determined by\r\n"
" following rule:\r\n"
" if start <= end then step = 1, otherwise step = -1.\r\n"
" start, end and step are divided by space.\r\n"
".SH EXAMPLES\r\n"
" \r\n"
"EXAMPLES:\r\n"
" * Sample FOR loop - listing all .txt files:\r\n"
" echo -off\r\n"
" for %a in *.txt\r\n"
" echo %a exists\r\n"
" endfor\r\n"
" \r\n"

" # \r\n"
" Sample1> echo -off\r\n"
" file1.txt exists\r\n"
" file2.txt exists\r\n"
" \r\n"
" * Theoretically it is legal for 2 nested FOR commands to use the same\r\n"
" alphabet letter as their index variable, for instance, a: \r\n"
" #\r\n"

" \r\n"
"NOTES:\r\n"
" 1. The GOTO command directs script file execution to the line in the script\r\n"
" file after the given label. The command is not supported from the\r\n"
" interactive shell.\r\n"
" 2. A label is a line beginning with a colon (:). It can appear either after\r\n"

" done forward in the script file, from the current file position. If the\r\n"
" end of the file is reached, the search resumes at the top of the file and\r\n"
" continues until label is found or the starting point is reached. If label\r\n"
" is not found, the script process terminates and an error message is\r\n"
" displayed. If a label is encountered but there is no GOTO command\r\n"
" executed, the label lines are ignored.\r\n"
" 3. Using GOTO command to jump into another for loop is not allowed,\r\n"
" but jumping into an if statement is legal.\r\n"

".SH DESCRIPTION\r\n"
" \r\n"
"NOTES:\r\n"
" 1. The IF command executes one or more commands before the ELSE or ENDIF\r\n"
" commands, if the specified condition is TRUE; otherwise commands between\r\n"
" ELSE (if present) and ENDIF are executed.\r\n"
" 2. In the first usage of IF, the EXIST condition is true when the file\r\n"
" specified by filename exists. The filename argument may include device\r\n"
" and path information. Also wildcard expansion is supported by this form.\r\n"
" If more than one file matches the wildcard pattern, the condition\r\n"
" evaluates to TRUE.\r\n"
" 3. In the second usage, the string1 == string2 condition is TRUE if the two\r\n"
" strings are identical. Here the comparison can be case sensitive or\r\n"
" insensitive, it depends on the optional switch /i. If /i is specified,\r\n"
" it will compare strings in the case insensitive manner; otherwise, it\r\n"
" compares strings in the case sensitive manner.\r\n"
" 4. In the third usage, general purpose comparison is supported using\r\n"
" expressions optionally separated by AND or OR. Since < and > are used for\r\n"
" redirection, the expressions use common two character (FORTRAN)\r\n"
" abbreviations for the operators (augmented with unsigned equivalents):\r\n"
" - Expressions : Conditional expressions are evaluated strictly from left\r\n"
" to right. Complex conditionals requiring precedence may\r\n"
" be implemented as nested IFs.\r\n"
" The expressions used in the third usage can have the\r\n"
" following syntax:\r\n"
" conditional-expression := expression |\r\n"
" expression and expression |\r\n"
" expression or expression\r\n"
" expression := expr | not expr\r\n"
" expr := item binop item | boolfunc(string)\r\n"
" item := mapfunc(string) | string\r\n"
" mapfunc := efierror | pierror | oemerror\r\n"
" boolfunc := isint | exists | available | profile\r\n"
" binop := gt | lt | eq | ne | ge | le | == | ugt | ult |\r\n"
" uge | ule\r\n"
" - Comparisons : By default, comparisons are done numerically if the\r\n"
" strings on both sides of the operator are numbers\r\n"
" (as defined below) and in case sensitive character sort\r\n"
" order otherwise. Spaces separate the operators from\r\n"
" operands.\r\n"
" 5. The /s option forces string comparisons and the /i option forces\r\n"
" case-insensitive string comparisons. If either of these is used, the\r\n"
" signed or unsigned versions of the operators have the same results.\r\n"
" The /s and /i apply to the entire line and must appear at the start of\r\n"
" the line (just after the if itself). The two may appear in either order.\r\n"
" 6. When performing comparisons, the Unicode Byte Ordering Character is\r\n"
" ignored at the beginning of any argument.\r\n"
" 7. Comparison Operator Definition:\r\n"
" gt : Greater than\r\n"
" ugt : Unsigned Greater than\r\n"
" lt : Less than\r\n"
" ult : Unsigned Less than\r\n"
" ge : Greater than or equal\r\n"
" uge : Unsigned greater than or equal\r\n"
" le : Less than or equal\r\n"
" ule : Unsigned less than or equal\r\n"
" ne : Not equal\r\n"
" eq : Equals (semantically equivalent to ==)\r\n"
" == : Equals (semantically equivalent to eq)\r\n"
" 8. Error Mapping Functions are used to convert integers into UEFI, PI or OEM\r\n"
" error codes.\r\n"
" Functions used to convert integers into UEFI, PI or OEM error codes:\r\n"
" UefiError : Sets top nibble of parameter to 1000 binary (0x8)\r\n"
" PiError : Sets top nibble of parameter to 1010 binary (0xA)\r\n"
" OemError : Sets top nibble of parameter to 1100 binary (0xC)\r\n"
" Each function maps the small positive parameter into its equivalent error\r\n"
" classification.\r\n"
" For example:\r\n"
" if %lasterror% == EfiError(8) then # Check for write protect.\r\n"
" ...\r\n"
" 9. Boolean Functions may only be used to modify operators in comparisons.\r\n"
" The following built-in Boolean functions are also available:\r\n"
" IsInt : Evaluates to true if the parameter string that follows\r\n"
" is a number (as defined below) and false otherwise.\r\n"
" Exists : Evaluates to true if the file specified by string exists\r\n"
" is in the current working directory or false if not.\r\n"
" Available : Evaluates to true if the file specified by string is in the\r\n"
" current working directory or current path.\r\n"
" Profile : Determines whether the parameter string matches one of the\r\n"
" profile names in the profiles environment variable.\r\n"
" 10. No spaces are allowed between function names and the open parenthesis,\r\n"
" between the open parenthesis and the string or between the string and\r\n"
" the closed parenthesis. Constant strings containing spaces must be\r\n"
" quoted.\r\n"
" 11. To avoid ambiguity and current or future incompatibility, users are\r\n"
" strongly encouraged to surround constant strings that contain\r\n"
" parenthesis with quotes in if statements.\r\n"
" 12. Allowable number formats are decimal numbers and C-style case\r\n"
" insensitive hexadecimal numbers. Numbers may be preceded by a\r\n"
" "-" indicating a negative number.\r\n"
" Examples:\r\n"
" 13\r\n"
" 46\r\n"
" -0x3FFF\r\n"
" 0x3fff\r\n"
" 0x1234\r\n"
" 13. Unsigned values must be less than 264. Signed integer values are bounded\r\n"
" by -/+263.\r\n"
" 14. Numbers are internally represented in two's compliment form. The\r\n"
" representation of the number in the string has no bearing on the way\r\n"
" that number is treated in an numeric expression - type is assigned by\r\n"
" the operator. So, for example, -1 lt 2 is true but -1 ult 2 is false.\r\n"
" 15. The IF command is only available in scripts.\r\n"
" 16. The ELSE command is optional in an IF/ELSE statement.\r\n"
".SH EXAMPLES\r\n"
" \r\n"
"EXAMPLES:\r\n"
" * Sample script for "if" command usages 1 and 2:\r\n"
" if exist fs0:\myscript.nsh then\r\n"
