If REDEF <name> INIRE, INIPO; INICF; PRLOC is used to change the behavior of a system
variable or GUD, the machine data DEFAULT_VALUES_MEM_MASK must be set to 1
(memory for initialization values active). Otherwise, alarm 12261 "Initialization not allowed" is
output.

Note, however, that when the INI attributes for these variables are set, that an
appropriately large memory for INIT values, can be set using MD 18150:
MM_GUD_VAL_MEM, must be available. In the machine data 11270:
DEFAULT_VALUES_MEM_MASK must be set to 1 (memory for initialization values
active). Too small a memory cause alarm 12261 "Initialization not allowed".
For R and system variables it is not possible to specify a default that deviates from the
compiled value. However, resetting to the compiled value is possible with INIPO, INIRE,
or INICF.
compiled value either (like for definition of the data item).
Only the INIPO attribute is permissible for global GUD (DEF NCK INT_MYGUD).
Only the data in the corresponding channel is initialized for channel-specific GUD (DEF
CHAN INT_MYGUD) with the corresponding result (RESET, BAG-RESET or NewConfig).
Example: 2 channels are defined with the channel-specific GUD that is to be initialized
during RESET:
DEF CHAN INT _MYGUD
REDEF _MYGUD INIRE
During a RESET in the first channel, the GUD for this channel is reset and the value in
the second channel is not affected.
