Uninterruptible procedures

If BS2000 system procedures are protected against interruption by the caller by means ofINTERRUPT-ALLOWED=NO then the following applies to EDT:

• It is not possible to switch to system mode by means of [K2].

• If EDT procedures are aborted by means of [K2] then EDT issues the message EDT0913 to ask whether any actions are to be performed.

• In interactive mode and when input is read from a file (read with RDATA from SYSDTA, processing of an EDT start procedure), the statements with security implications – @SYSTEM, @EXEC, @RUN, @LOAD, @UNLOAD and @USE – are rejected unless the statements are issued by the protected procedure itself (SYSDTA=SYSCMD).
