Does anyone know how the DCL SHOW/MEMORY and SHOW/SYS commands decide how many pages of physical memory are free / busy? Although SYS$GETSYI seems like the right idea, I don't see how to get the data I need. Please reply directly. Thanx, keh kholt@bbncc3.ARPA

They probably get the data from the system globals SCH$GL_FREECNT, SCH$GL_MFYCNT, and SCH$GL_PHYPGCNT. How you reference these depends on the language you are using, but basically, you declare them to be external symbols and resolve them at link-time by linking with $ LINK MYPROG,SYS$SYSTEM:SYS.STB/SELECTIVE_SEARCH or some such incantation.
