We have an old REXX exec that I had to modify. This is a rather simplistic description but it consists of 2 parts - 1 to set up the environment(variables) and 2 to use the variables setup in 1. Bottom I had problems modifying it so I re-wrote it.
The original used GLOBALV extensively - part 1 would do PUTs and part 2 would do GETs. Besides a lot of 'steam lining' I thought I would be 'clever' and changed the GLOBALVs to 'PIPE var VarName 1 | var VarName'. However the new exec ran much slower than the old. I then did a test to only compare GLOBALV PUT/GET to setting and retrieving the variable with PIPE var stage. The pipe stage was much slower. I thought the pipe logic would be better - obviously mistaken. Any comments - any other method I could have used that is perhaps faster than GLOBALV? Thanks Peter
