USER^ATTRIBUTES
USER^ATTRIBUTES is impossible, because at that point memory for the DCBs has
already been allocated. Also, because SCF messages are picked up only after this
allocation is complete, changing EXTSUSIZE by means of SCF is impossible.
See the SCF Reference Manual for GDSX for more information on these attributes.
status returned value
INT:value
is the returned value. The value of status is generated by a TAL RETURN
statement in USCODE and is one of the following:
scf-command input
INT:value

the following:
su-object-type input
INT:value
is the SU object type, and is always equal to 21.
request-object-name input
INT:ref:12
is the object name for this request, a two- or three-level name specified in the ADD
