but why not simply try it ?
enrico..you wound me sir! Of course I tried it!
reformatted a bit to get in in three lines, but the error message is:
Menu RefList RefMode Utilities Workstation Help
Edit Entry Panel Invalid command
Command ===> SWAPBAR
I did follow the index as shown above and sure enough, the swapbar command is there if you go through the SWAP tutorial and press enter to get that secondary list.
I'm wondering if the terminal settings make a difference, like command line position and terminal type/width.
