1. docker exec -it mvs38j c3270 localhost:3270

6. To logoff, you can enter LOGOFF then Ctrl+] and type quit at the c3270 prompt

⁠Clean shutdown

⁠Some commands to try

• LISTCAT to show your datasets
• HELP LISTCAT gives help on LISTCAT command (F3 to quit help). Inside help viewer, type + then enter to advance to next page and likewise - to go back to previous page.
• HELP lists standard TSO commands (note some are not installed, e.g. CALC, mainly due to copyright restrictions) and HELP UTILS lists additional commands that come with TK4-

⁠Problems

• Attempt to logon as HERC01 fails with IKJ56425I LOGON REJECTED, USERID HERC01 IN USE. Unlike Unix-like systems, TSO disallows concurrent login sessions for same user. To resolve this, you need to kill HERC01's session, which you can do by going to http://localhost:8038⁠ and enter the console command /C U=HERC01. (Another method is to login as HERC02, with same password, enter option 3 and press enter, type OT and press enter, and then type /C U=HERC01 and press enter.)
• Stuck at prompt REENTER+ - Ctrl+] then enter command pa 1. (This is the equivalent of pressing the PA1 key on a physical 3270 keyboard, which cancels the current command, like Ctrl+C on DOS/Windows/Unix.)
