RE: MCH1201 (Rcvr too small) on an _if_ statement???

["Wilt, Charles" <WiltC@xxxxxxxxxx>]

While I agree a *PSSR is easily abused, the flip side is that is easily taken advantage of also.

A shop standard involving an /INCLUDEd *PSSR that perhaps dumps the job, takes a copy of the screen,
display's a nice message to the user, and notifies IT would make life easier.

As a practical matter, making sure the user does not see a system generated error is part of the OWASP
Top-10 which has been adopted by PCI.
