BMS, DSPF, and MFS Map Preview

The Source Viewer maps tab renders linked screen maps as a visual green-screen layout and lets you assign screen types. Multiple linked maps appear in an accordion.

• BMS — CICS 3270 map definitions.
• DSPF / DDS — IBM i 5250-style display files (.dspf, .dsp, .dds).
• MFS — IMS device formats (.mfs). Message chips switch between the whole screen and a MID or MOD descriptor.

Map previews derive from source descriptors; they are not live 3270, 5250, or IMS Connect sessions. For IMS details, see the IMS COBOL and MFS Maps topic.
