Hi D sh,
If we are not giving P, it will give error.
For dealing with symbols, we may need to convert the char string to picture string P.
But & is a specific case. The ISPF macro is not able to find & (ambersand) string in the Jobs / PROCs.
The solution is that we need to first convert the ambersand to ? or $ symbol and then do the process.
After that convert it back to & (since there may be lot many & used in other areas in the job too).
