JZLOG - processor logging

This gives control over the amount of information printed about the operation of the processors:

CALL JZLOG (chOPT)

chOPT is a CHARACTER string whose individual letters select particular outputs:

A

monitor each call to JZIN

B

monitor and dump the call bank (implies option A)

C

monitor and dump the parameters (implies option A)

E

print error messages only

N

reset to normal logging

Q

suppress all messages

T

monitor each call to JZTELL

X

monitor each call to JZOUT

Y

monitor and dump the call bank (implies option X)

The implementation of the effect of options B, C, Y, is waiting for other new code in Zebra, e.g.,

          CALL JZLOG ('E')
          CALL JZLOG ('TBCY')      maximum logging
          CALL JZLOG ('A')         log only entries
          CALL JZLOG ('N')         back to normal
