This may be a bug on your version or platform; I do a similar thing with no problem. Are you sure the TERM and TERMCAP you have set while in 4GL is ok? i.e.: Does running vi on the same file straight from the OS work ok? If DISPLAY "" help, try a CLEAR SCREEN just to see what happens then. >My questions is: How to I tell Informix that I need it to 'release' >the screen temporarily, run the command, and then return to normal? >I tried putting 'DISPLAY ""' before the run statement and it seemed >to work a little better. >I also need a easy way to re-display the Informix-4GL screen after the >command returns. The RUN command, when used without the WITHOUT WAITING clause, should repaint the screen for you. If not satisfactory, try CURRENT WINDOW IS SCREEN. >Any help would be *most* appreciated!
