Help Requested!!!
I'm trying to find a way to disable the Command Line Recall mechanism
implemented by the VAX operating system. I'm trying to develop a spreadsheet
type input facility in which a user may use the cursor keys to position
himself on the screen. Currently under VAX/VMS, the UP and DOWN cursor
keys invoke the Command Line Recall procedures provided by the op-sys.
Can anyone out there offer a solution?????

See page 8-3 of the I/O User's manual, volume 1. The SET TERMINAL/NOLINE_EDIT command disables most terminal driver editing functions, but then you have to be certain to save the original characteristics and restore them when you're done. A better approach is to perform your I/O with $QIO and use the TRM$M_TM_NORECALL modifier to disable the recall mechanism, or other modifiers as necessary to disable interfering features of the driver. Check out section 8.4.1, the Read function. ---- Ed McGuire, Systems Coordinator, Grinnell College, MCGUIRE@GRIN2.BITNET
