SFBLOK DSECT
Cross Reference (Contains links to field and bit definitions)
SFBLOK Prolog
NAME : SFBLOK
DESCRIPTION: VM/SP 370 SPOOL FILE CONTROL BLOCK
DSECT : SFBLOK
FUNCTION : THIS DSECT IS USED TO WHEN SPOOL FILES ARE TO BE
TRANSLATED TO VM/SP FORMAT. (IT IS ANALOGOUS TO
THE VM/XA SPFBK.)
CREATED BY : HCPSXSFB FOR SPFBK TO SFBLOK TRANSLATIONS. THIS IS
DONE FOR DIAGNOSE X'14' AND SPTAPE COMMANDS.
DELETED BY : NOT APPLICABLE

The following 4 bytes are reserved for SPTAPE to save spool file
information that is not available on the VM/370 systems such as VM/ESA
Release 1.5. This data is also saved here when Diagnose x'14' and *SPL
return an SFBLOK to the user. In particular, the bits that are useful
to Diag x'14' and *SPL are the ones which indicate the KEEP/NOKEEP
status (SFBXKEEP) and the MSG/NOMSG status (SFBXMSG) of the file.
