OSFST OSFST describes the fields of an OS file status table. When an OS disk is accessed, DMSROS obtains storage from CMS free storage, builds and fills in an CSFST block, which
is ccmparable to a CMS FST block. This block is released by DMSALU. o OSFSTFM 1///////////1 OSFSTFVF S OSFSTLRL A*1 1///////1 A*2 1 A*3 10 OSFSTNXT OSFSTCER 1S OSFSTEND .J 20 OSFSTDSN 4S 50 OSFSTXTN FO OSFSTTYP FS OSFSTNTE 1////////////////////
