What is UX? What shell were you using on UX? And what version of that shell were you using on UX?

What shell are you using on AIX? And what version of that shell are you using on AIX?

The diagnostic you showed us says the error is on line 80 in your script, but you have shown us much less than 80 lines.

If looks like you are defining a function MENU_INTRO() and inside that function definition you are defining another function onstat_p() . Standard shell syntax doesn't allow a function to be defined inside another function.
