Right Hand Pointer

M42, Invalid QUIT within a TRANSACTION

Introduced in the 1995 ANSI M[UMPS] language standard.

Transactions are delimited by a TStart and TCommit commands. A TCommit command must occur at the same or a deeper Do level than the corresponding TStart command.

When a TStart command has been executed, and a Quit command is executed that returns from the Do level at which the TStart command was encountered, this error will occur.

Do INIT,PROCESS,EXIT
Quit
;
INIT ... TStart ... Quit
PROCESS ... Quit
EXIT ... TCommit ... Quit

The above processing model is not compatible with transaction processing. The complete definition of a transaction must be in one Do-able module.
