Question:
In FPW 2.6 I often get a ‘variable not found’ message when the read statement executes. This usually happens only the first time the screen is used in the program. Accessing the screen again will not cause the error. The ONERROR does not trap this error, and the dialog does not say what variable is not found. How do I track this down?
Answer:
You may want to open the SPR file and check the READ statement to see whether it has a variable that has not been defined.
For example:
READ VALID glTestVariable
You could put a SET STEP ON before the READ, and check the value of the variable.
