As Tom M mentioned, there are "commonly" encountered general situations.
It seems the same question would apply to almost any error encountered; Operation exception is probably one of the easier ones to diagnose in many cases. Some of the "commonly" would be * Wild branch to uninitialized storage at which the data is not a valid instruction * Branch to 0 because of an uninitialized pointer, at which the data is not normally a valid instruction * Use of an instruction that is not valid on the machine on which your program is running Peter Relson z/OS Core Technology Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
