_COMMANDCOUNT - QB64Official/qb64 GitHub Wiki

The _COMMANDCOUNT function returns the number or arguments passed from the command line to the COMMAND$ function.

Syntax

result& = _COMMANDCOUNT

Description

• 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(s)

The code below gets the number of parameters passed to our program from the command line with _COMMANDCOUNT:

limit = _COMMANDCOUNT
FOR i = 1 TO limit
    PRINT COMMAND$(i)
NEXT

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).
