Command$

Program flow control function.

The Command$ function allows a calling script to use the parameters from the called script.

Syntax

var$=command$(<number>)

Parameter

<number>, numeric: the number of the parameter on the command line used to launch the script. Number 0 is the name of the script itself (including its path). So command$(0) will always return the full name of the running script. Parameters are strings separated by blanks.

Return value

var$ gives the <number> parameter on the command line used to launch the script. If the parameter <number> does not exist, an empty string is returned.
