{{PageDescription}}
|
|
* The function returns the number of arguments passed from the command line to a program when it's executed.
|
|
* Arguments are spaced as separate numerical or text values. Spaced text inside of quotes is considered as one argument.
|
|
* In c, this function would generally be regarded as 'argc' when the main program is defined as the following: int main(int argc, char *argv[])

''Example:'' The code below gets the number of parameters passed to our program from the command line with _COMMANDCOUNT:
|
|
{{CodeStart}}limit = {{Cl|_COMMANDCOUNT}}
|
|
{{Cl|FOR...NEXT|FOR}} i = 1 {{Cl|TO}} limit
|
|
{{Cl|PRINT}} {{Cl|COMMAND$}}(i)
|
|
{{Cl|NEXT}}
|
|
{{CodeEnd}}
|
|
: ''Explanation:'' If we start ''ThisProgram.exe'' from the command window with '''ThisProgram -l "loadfile.txt" -s "savefile.txt"''', the _COMMANDCOUNT would be 4, "-l", "loadfile.txt", "-s", "savefile.txt" command arguments passed to the program, which we could then read separately with COMMAND$(n).
