7.2 POSIX command line ¶

Algol 68 programs can access the command-line arguments passed to them by using the following procedures.

Procedure: argc = int ¶

Procedure that yields the number of arguments passed in the command line, including the name of the program.

Procedure: argv = (int n) string ¶

Procedure that yields the nth argument passed in the command line. The first argument is always the name used to invoke the program. If n is out of range then this procedure returns the empty string.
