CICS COBOL / BMS migration

Convert CICS COBOL screen programs with BMS maps into runnable legacy code on the JVM you can play in OL Next, map player, not a 3270 terminal.

OL Next converts CICS COBOL programs that use BMS maps into runnable legacy code on the JVM through the cobol-cics kit. Teams import .cbl source, .bms maps, and copybooks, then generate and validate behavior in the browser player, without a mainframe. Legacy teams keep editing the COBOL in OL Next; the program runs off the host. Play converted maps in a map-layout grid (not a 3270 terminal). For data, use an H2 sandbox (schema.sql / seed.sql), the live host store (DB2, VSAM, or IMS-DB via JDBC or OL CoreIQ APIs), or a modern DB after data migration. See DB access management.
