Whether there is an analogue of command ZQ in GT.M.
What is ZQ?

In MSM, it is used in an error trap: "Error processing will continue at the
next higher execution level as if the error had not been trapped at the
current level."

For example, suppose your error handler is prepared to handle a <DSCON>
error, but that's not what caused the error, then ZQUIT will allow a
higher-level error handler to take over.

In Cache:
 "Argumentless ZQUIT clears the entire stack."
  "ZQ expression unwinds the stack to another call stack level with a $ZTRAP
error handler. The value of expression specifies the number of
handler-specified stack levels ZQUIT unwinds. If you use 1 as expression,
Caché unwinds the stack to the first encountered $ZTRAP handler. If you use
2 as expression, Caché unwinds the stack to the second encountered $ZTRAP
handler, and so on."

[KSB] Thanks Maury. Looks like Chris' response was the right one.
