POSIX command line (The GNU Algol 68 Compiler)

### 8.2 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 `n`th 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.
