Masking Script Information (VTAM)
Masking ignores specific areas of the screen when performing comparisons. Masks can be put directly into a formatted script using ISPF Edit or indirectly using the online masking command. If you enter a mask, it stays in effect until you enter the XMASK command or exit Performance Test for VTAM.
There are two basic mask types:
- Row masks are characters inserted into a formatted script to mask an entire screen row or selected columns within the row.
- Generic masks use a parsed string allowing you to make conditional masking decisions based on screen content. You can put generic masks within a formatted script.
Masking is not available for unformatted scripts.
