Maybe I don't know what exactly defines what an *Escape message is, but
Monitor in a procedure that has a procedure call within it will have
that procedure's error caught.
Example:
This monitor will catch any errors encountered in the callProc
procedure.
Monitor;
callProc();
On-Error;
EndMon;
I try to put Monitor statements in most/all of my exported procedures
and have seen them catch errors in subsequent internal procedure calls.

Then what is???

it is no where as comprehensive and feature rich as exception handling
in java or c#. In RPG if an *escape message is sent to a procedure
lower on the invocation stack, your on-error ... endmon code will not be
executed. In C#, the try ... finally handler will be called. You can
rig the equivalent to try finally in RPG and ILE, but it is a lot of
code.
