Appendix B: eMS/DOS Macro Library in this contains a DOS macro library with the followina
significant entries. I more complete list may te -obtained by invoking the DOSalCRO EXEC; this EXEC produces a list of all the macros in the DOS library.

Returns address of background partitions coa.unication
region; expands to SVC 33. Normal processing termination; expands to SiC O. Activates a data file; siaulated by D!!SOR1, D!!SOR2, D!!SOR3. Provides/terminates supervisor linkage to user's prograa
check routines; siaulated by DaSDOS. DSECT for VSA!! ACB (access method control block). DSECT for VSA8 EXLST control block (contains addresses of
user exit routines. DSECT for iSA8 RPL (request paraaeter list control block). DSECT of system co.munication region. DSECT of abnorMal termination option table. DSECT of Boundary Box; contains beginning and ending
addresses of background partitions communication region. DSECT of background communication region. DSECT, CMS/DOS first in class table. DSECT, CMS/DOS number in class table. DSECT, program check option table. DSECT, program inforaation block extension. DSECT, program inforaation block. DSECT, physical unit block ownership table. DSECT, DOS/VS anchor table. DSECT, describes fields in the logical transient area (tTl). DOS/iS fetch table containing fetch/load parameter list. DSECT defines fields of CMS/DOS physical unit block (PUB). DSECT same usage as KAPPOB. DOS simulation control block used for the siaulation of the cas file control block (FCB). DSECT, work area for D!S!CP Creates CMS/DOS control blocks for DMSNUC. DSECT for CaS/DOS logical unit block.
