Starting with 1.2, I believe IoErr() will return pr_Result2 from the
program that was executed (pr_Result2 returns the AmigaDOS error code,
like 214 == "disk write-protected").  This is not the same as the return
code from the program, so "exit(25)" in a C program will show up as a
0 return value from IoErr()--you have to explicitly set pr_Result2 to
a value to use this from C.  If you are running WShell with Bill Hawes' 
patches to Execute(), then you get more useful information, but that's 
obviously non-standard.

(This is based on a vague recollection of something Andy Finkel said
on BIX long ago and far away.  I'd check it, but I have Bill Hawes'
patch installed...)
