Version 7.6 of FOCUS for Mainframe runs on any IBM or plug-compatible computer that supports z/OS.

Note for MVS/ESA and OS/390 users: Assume that references to z/OS throughout this manual apply equally to MVS/ESA and OS/390 unless otherwise indicated in the text. Please contact the Information Builders Customer Support Services Department in New York for details.

FOCUS is configured to take maximum advantage of the IBM z/OS Extended Link Pack Area (ELPA). Installing the re-entrant part of FOCUS in ELPA allows more sharing of FOCUS code among users and requires a smaller logon region size.

Note: FOCUS 7.6 is a fully compliant LE program and requires IBM LE in order to run.
