Using the "Evaluate" function

[davidnickerson]

I'm having a bit of trouble getting my head around when to use this. FM Help gives an example (2+2 in the field; Evaulate returns 4), but the real-world examples puzzle me. It seems to be used quite a bit when calling Get (ScriptParameter), as in the following example:

GetAsText ( Get ( CurrentTimeStamp ) ) &

“ - Changed by: “ & Get ( AccountName ) &

“ - Field: “ & Get ( ScriptParameter ) &

“ Changed to: “ & Evaluate ( Get ( ScriptParameter ) ) & ¶ &

Evaluate ( ( LeftWords ( Get ( ScriptParameter ) ; 1 ) & “::z_

AuditTrail” ) )

How is Evaluate ( Get ( ScriptParameter ) different than just Get ( ScriptParameter ) ?

Thanks for your help.

As rarely as possible.

Example: say the script parameter contains the string "Textfield", and that you have a field named Textfield that contains the string "some text". In this case:

Get ( ScriptParameter ) returns "Textfield";

Evaluate ( Get ( ScriptParameter ) returns "some text".
