>>>What is the sequence in which error handling is processed? In my particular instance, I'm trying to remove from a page in a pageframe all labels of a certain name. I'm doing this in the valid of a textbox on the main form. My code is

When I stepped into the offending line of code in the TRY block the next line of code in the debugger was from the form error handler. It didn't even point to the EXIT line in the CATCH block.

Hi Rich,

Not sure why the on error is firing, but the problem is deeper (and in this case your issue with it is moot), your code will never work as you are expecting, you will enter an infinite loop as the EXIT will exit the try catch block, not the DO WHILE as you are thinking, if you do not believe me or the help (look for EXIT COMMAND: "Exits a DO WHILE, FOR, SCAN, or TRY…CATCH…FINALLY structure.") then try this simple program:

set escape on && I am such a nice guy...
do while .t.
	try
		abc
	catch to loException
		? loException.Message
		exit
		? 'I am never printed'
	endtry
enddo

Enjoy infinity :)
