I’m putting together some education materials for new z/OS users, and would like a list of common or favourite commands (the commands your fingers know without having to think about them).  If you have any more useful commands, please tell me and I’ll add them.

If there is enough interest I can make the commands into html links to the online manuals – if so please let me know.

Useful links

• Useful z/OS books including ABC

Console commands

Managing the 3270 console

• k a,ref shows areas on operator console
• k a,none – removes “out of line area” from console.  You may need to do k e,d to remove the area first
• k a,14 makes the area 14 lines deep
• k a,6,6 makes two areas A and B, can then use D A,L,L=B for to display the command  D A,L in window B

Some commands,  eg display commands comes up in a “out of line” frame at bottom of the screen

• k d,f scroll forward, sometimes pf8 does this. Check with d pfk
• k e,d remove the bottom “out of line display” area

Screen

• k q clear the backlog of queues messages
• k e clear the scrolling messages
• k s,ref display the current settings
• k s,del=rd have message scroll off the top automatically
• k s,del=n stop messages scrolling off the top
• k e,n  remove nth message from the top of the screen – useful of the messages do not scroll.
• d pfk
• k n,PFk=(001,CMD=’d a,l;d ts,l’) sets the pf key to the command strings separated by ;
• PA1 retrieve previous command

If you lose the console

• v 700,offline
• V CN(L700),ONLINE
