SETPOSTPROC

(Re)set POSTPROC field of a datafile

    A = SETPOSTPROC(A,MAPPING)
    A = SETPOSTPROC(A)

Input
A	Datafile
POSTPROC	Postprocessing mapping command

Output
A	Datafile

Description

Sets the mappings stored in A.POSTPROC. The size of the datafile  A is set to the output size of MAPPING.  A call without MAPPING clears A.POSTPROC. The size of the datafile  A is reset to undefined (0).

The mappings in A.POSTPROC may be extended by ADDPOSTPROC.

Mappings in A.POSTPROC are stored only and executed just  after A is converted from a DATAFILE into a DATASET.
