PURGEX Explicit data block purge
Flags a data block as empty.
Format:

Output Data Blocks:
DBi Any data block.
Parameter:
PARM Input-integer-default=0.
Remark:
PURGEX
Explicit data block purge
PURGEX is an executive operation module intended for restart purposes only. If at
execution time a data block has been previously output from a module, then any
existing data will be deleted and the data block will be marked as empty. If the data
block has not been previously output from a module, it will simply be marked as
empty. A purged data block is equivalent to a data block not generated with the
exception that the NES "remembers" for restart purposes that it has been previously
output. If no restart is involved, purge is entirely equivalent to a data block not
generated.
Example:
< 0 The data blocks are deleted and marked empty.
≥ 0 No action is taken.
Flag data block MGGX as empty so as to avoid execution of EMA module on restart.
