ANCHSECT ANCHSECT defines the DOS/VS anchor table. This DSECT is used by DMSDCS when a CDLOAD (SVC 65) is issued, and the phase is not found in either the CMSVSAM or CMSAMS segment.
In this case, the specified phase is loaded either from a CMS DOSLIB or a tOS core image
library, and the name, load point, entry point, and the length in bytes, of the phase are
saved in an available slot in the anchor table. ANCHSECT is invoked by the ANCHTAE macro,. 0 ANCHENDA 8 ANCHCBS 10 18 ANCHLDPT 20 A*1 ANCHPHLN Hexadecimal Pield tisplacement Name
