I'm getting a strange result when I try to initialize some stem
variables
whose stem names start with "o". I don't understand how the shell is getting
its fingers into an ordinary rexx assignment statement?
My system is OpenSuSE 13.1 on x86_64 hardware.
I ran across this while trying to set various opt.X variables, so I
tried
changing opt. to optn.. When the problem persisted, I created a little
testcase program. Here's what I have:
| 18:42:08,leslie@pinto
| ~/bin/rexx
| $rexx -v
| Open Object Rexx Version 4.2.0

| 18:42:41,leslie@pinto
| ~/bin/rexx
| $cat testcase
| #!/usr/bin/rexx
| trace rnormal
| o. = ''
| op. = ''
| opt. = ''
| opti. = ''
| optio. = ''
| option. = ''
| optn. = ''
| o.'a' = 'alt'
| op.'B' = 'amb'
| opt.'c' = 'cap'
| opti.'C' = 'col'
| optio.'n' = 'num'
| option.'H' = 'sha'
| optn.'s' = 'sec'
| exit
| 18:42:54,leslie@pinto
| ~/bin/rexx
Can anyone explain what's happening here?
Leslie
btw
There is an empty file 0 in my bin/rexx/ directory; some arcane
subsystem on
my machine creates one in every directory, so if I delete it it's back the
next day; so that's where the error message gets it, but how is bash getting
invoked during a Rexx assignment?
