EMACROS are used by assembly programs to set up linkages and to create register linkages. ESTART and ERETURN set up standard linkages for DOS/360. EREGS defines symbolics for registers.
BLKPRT
Version 1.1.0 - updated 08/31/2011
BLKPRT simply accepts an eight character string and returns it as 12x12 block letters, suitable for separator pages. Letters may be formatted as slanted or straight. In case your wondering, this code was copied from the JES2 printer driver. Despite this, it has no operating system calls.
Included is an Assembler program to demonstrates how to call BLKPRT.
