It is not clear what development environment is being used here.
The phrasing of "Parameter Id" and the use of the F1 function key to find it my guess is this is about ABAP development ... and if that is the case you might want to repost to the ABAP Development SCN discussion forum (see http://scn.sap.com/thread/1347461 for an example posting that may be related).
If this is not ABAP but is related to SQL Anywhere please identify the API, language and development environment; providing a bit more background for the question.
