Handle Ignore and Resp which one to use
CICS Handle conditions should be avoided at all costs. They lead to unstructured complicated convoluted logic and code.
Handle conditions where required in the days before CICS had the RESP as part of it's repetoir.
Handle conditions cause the program to jump to the specified label when the condition occurs, and so is an implicit use of a "go to" statement.
Today CICS allows us to use the RESP as part of the EXEC CICS command which means we can evaluate the response immedietly after the exec CICS command has been executed and appropriate logic can be codded without a "go to". This means more structured and easier to use code.

If I was QA'ing your code and you used a Handle condition, your code would fail the QA and be returned to you to fix.
