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[])
Examples
Example: 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).
