Parameterizing the TCD Command Interface

Use

You can parameterize the input and output fields of screens. Regardless of the type of parameterization, you always enter the parameter in the VALIN column of the command interface. The content of the Mode column determines whether a field is for input or output, and after parameterization, whether it is for setting, getting, or checking the field value.

Parameterizing Input Fields

You must set the field mode to ‘S’, and enter a literal or the name of a parameter in the VALIN column. At runtime, the screen field will be filled with the value that you specified.

Parameterizing Output Fields

Reading a Value

You must set the field mode to ‘G’, and enter the name of a parameter in the VALIN column. At runtime, the parameter will be filled with the value from the screen field.

Checking a Value

You must set the field mode to ‘C’, and enter a literal or the name of a parameter in the VALIN column. At runtime, the screen field will be checked against the value that you specified. If the values are different, the script will fail.
