Mainframe Computing
Mainframes and midrange systems are taught as enterprise computing platforms optimised for reliability, transaction scale, batch processing and long-lived workloads.
Enterprise computing continuity
Mainframes optimise transaction scale, reliability and batch/enterprise integration; they are not simply larger personal computers or supercomputers.
COBOL, PL/I, Java, Assembly, SQL and REXX with JCL, TSO and enterprise datasets/queues.

Fujitsu GS21 / OSIV, NEC ACOS and Hitachi VOS3/US remain research comparison anchors.

PL/I, JCL, REXX, CLIST, HLASM, DCL, Ada/SPARK, BLISS, pTAL, TACL, ALGOL and WFL extend the permanent 23 language tracks rather than replacing them.
All existing public simulation, Coding Studio, Intelligent Coding and current working pages remain unchanged. New HEPC features start from the new Programming Studio onward.
