The Signal handling in Object REXX



The handling of the halt signal seems to be buggy in Object-Oriented REXX; 
for example the signal handling does not work in the following REXX 
program. 
[Tested with OBJREXX 6.00 12 Jul 1996] 
[Fixed in OBJREXX 6.00 26 Feb 1997 and newer versions (included in WARP 4 
Fixpack #6)]

/* example for a bug in the signal handling in Object REXX            */
