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 *SPL OUTPUT. DELETED BY : NOT APPLICABLE RELOCATION CONSIDERATIONS : None
