Callx

[Aurora Benskin]

Subroutines invoked with the callx processing code are executed when an item in D3 is updated, regardless of which process does the updating. That is, the Update Processor, FlashBASIC write statement, TCL copy command, or the AQL t-load command. The entire item is passed to the subroutine.


This processing code differs from the call subroutine in that it is called any time an item in the file is updated, versus being called when the item is updated from the Update Processor. The parameter passed is the entire item, which may be updated by the subroutine. Only the following ACCESS functions are supported within a callx subroutine:

If a routine writes, deletes, or modifies an item in a file using a callx FlashBASIC program to validate the data and the validation fails, the item is not written to the file. This affects commands such as clear-file, delete-file, and t-load. Since the FlashBASIC write command has no then/else clause, the program cannot trap the write failure.
