GRASP: A PL/1 COMPATIBLE GRAPHICS SUBROUTINE PACKAGE FOR THE IBM 2260 DISPLAY STATION (LOCAL ATTACHMENT). VOLUME 1 - INTRODUCTION AND USER'S MANUAL

Abstract

GRASP is a set of PL/I compatible subroutines which provide programming support for the IBM 2260 Display Station in local attachment; i.e., the attachment of a 2260 directly to a System/360 CPU channel via the IBM 2848 Display Control. The subroutines are coded in OS/360 Assembler Language and are reentrant. They permit the PL/I programmer to manipulate the 2260 as an I/O device in the same manner available to the Assembler Language programmer using the Graphics Access Method under OS/360 (with restrictions as noted in the Introduction to Volume I of the document). All errors, except those which normally result in OS/360 abnormal ends (ABENDS), are returned to the user via subroutine parameters. GRASP IS DESIGNED TO OPERATE UNDER THE MFT configuration of OS/360. Volume I of the document gives an overview of the 2260 and an introduction to the GRASP routines. Volume II (AD-706 134) gives detailed program specifications.
