This configuration macro allows you to specify some rexx code which overrides any "reading" messages you may have set via the "/Reading" switch (or allowed to default).
Any symbols in this macro are replaced before each use. Depending on what you are doing, you may want to use the "/Reading" switch to set a blank entry because you will not be able to stop the first (and possibly other) "reading" messages as it will take a while to create the macro!
The rexx should generate whatever messages to the screen it wishes, the "cursor" position is at the start of a line.
The rexx code gets passed these variables:
