A night made portable programming example using the GNU Readline Library is available at http://vouters.dyndns.org/tima/Linux-HP-UX-OpenVMS-libreadline-GNU_readline_usage_example.html

Currently this programming sample has been successfully tested on both Linux Fedora 16 and OpenVMS IA64 V8.3-1H1. The produced sys$library:readline.tlb was missing the correct file protections so that it could be used by any account on a cc command. This has been corrected in the VMS descrip.mms producing the GNU Readline output files in their final location. I now realize I am also perhaps missing the correct VMS file protections when copying this software C headers into HP GNV /usr/include. Feedback by users would be welcomed.

The code at this URL above is awaiting for this week-end to come to be also fully tested on HP-UX B.11.31 IA64 using the provided information.

libreadline is designed to emit a BELL sound if the history buffer limits are attempted to be overcome with the arrow keys. This BELL sound fprint'ed to stderr was causing a new line on OpenVMS with the cursor one line underneath ifs expected position. For example, if your first command was 1+2 and you pressed the up arrow to recall an history non existant command, the display would look like:

PROMPT : 1+2

                          <cursor here>

If you typed exit where the cursor is, your last command would '1+2exit'. This problem specific to OpenVMS has just been corrected by avoiding the problematic fprintf(stderr,BELL).

A noew patch has been produced.

Dear OpenVMS user,

Two libreadline usage examples at:

http://vouters.dyndns.org/tima/Linux-HP-UX-OpenVMS-libreadline-GNU_readline_usage_example.html

and

In the hope this will interest among some of you.
