The term "global variable" has a specific meaning in programing: I suspect what you are trying to do with ksh, is actually something a little different, since usually in shell scripts all variables are global. So, can you tell us what you are actually trying to achieve?
Seeing as we've established ksh (yes ?), the nearest thing to a 'global' var is to 'export' it.
A var set/declared in a given shell level is avail to the code at that level.
You can export it, but this only makes it available to any sub-shells called from the current env. You cannot export (or 'return') a var upwards in the shell tree.
This is true of shell scripting generally ie bash, ksh, sh etc.
See the docs I linked to.
