Additional Parameters 

Definition

When executing an external command, you can include a character string of up to 128 characters containing additional parameters.

Prerequisites:

·        The use of additional parameters must be allowed for this command (standard).

Maintaining External Commands

·        The total length of all parameters (predefined and passed at runtime) cannot exceed the maximum length of 128 characters.

 

Placeholder

These additional parameters are generally added to the end of pre-defined parameters following a blank space. You can, however, also define placeholders for these additional parameters within the pre-defined parameters.

 

Table: Placeholders for Parameters

Placeholder	Purpose
'?'	used for required parameters
'&'	used for optional parameters

If no parameter values (or a blank character string) is passed at runtime for a required parameter, then the exception PARAMETER_EXPECTED is triggered. The placeholder '&' for optional parameters is removed in this case. Otherwise, the characters '?' and '&' are replaced with the parameter character string passed.
