Reverse the lock state (corresponding to QLOCK)

$\fbox {CALL QLREV (IREMC)}$

IREMC: (see 10.2.4).

All unlocked tracks will be locked.
All locked tracks will be unlocked provided that there is no other closed lock and, for composite particles, that there is no locked daughter, granddaughter, ... after the QLREV operation.

Calling QLREV a second time reestablishes the initial lock state. The mnemonic symbol XLREV(IREMC) is set to .TRUE. if the lock state is reversed. At the begin of the event processing and after calling QLZER(IREMC), XLREV(IREMC) is .FALSE..
