Using Dynamic Job Descriptor Entries (DJDEs)
5-6 Using LCDS Print Description Language
Restrictions on job parameter modification
To process a DJDE, the system must process data up to the
recognition and interpretation of the DJDE itself. This sequence
requires that the basic description of the input source must be
correct before the application of the DJDE. Therefore, you must
not change the description of the input source with DJDEs, either
by accident or by intent.
The system also does not allow certain basic parameters to be
changed through the selected JDE (the JDE specified by the
JDE DJDE).
NOTE: CODE changes to data may occur and take effect on the
page boundary following the DJDE record. If a translation code
change is involved in a selected JDE, the parameter portion of
any subsequent DJDE must be in the new code. The prefix used
by the IDEN must, however, retain the original hexadecimal
value. Thus, if the CODE changes from EBCDIC to ASCII, the
prefix must remain in EBCDIC even though the parameter
portion changes to ASCII.

specified in the JDE DJDE are listed in the following table.
