  • 1.  Clear and TPUT Clear fail

    Posted 06-22-2023 08:24

    The Rocket port of clear fails as does tput clear under TN3270 OMVS yet the IBM provided versions in /bin do work.

    Am I missing something with the Rocket versions?

    Hi Lionel, 

    Which version of ncurses are you using?

    Lionel,

    It doesn't seem to be Open AppDev version of ncurses. I tried a few versions (6.1-6.4)  and they work fine on my system. Could you check your version using clear -V command?

    This is the result of 'clear -v' from Rocket -

    HI,

    as I had mentioned in some previous private discussion: 

    The ncurses data for a "dumb" terminal do not have an attribute for 'clear', and the default for attributes is an empty string. Adding a '\f' as a attribute fixes the problem.

    Well, if one isable to decompile and recompile, I needed to do this on a linux machine.

    One solution to the pb is the following one liner to modify the termcap database:

    infocmp dumb | sed '$ s/$/ clear=\\f,/ '  | tic -

    best
