As a side project at work, I am to program in fortran on the vax. I don't want to use stardard text formatting for input and output in my programs. I was wondering if someone could tell me how to find out if there are any programming libraries for making graphical programs in the system (a default library path?)or maybe point me in the direction of information on how to do it without a built in library (much like java swing).
The main issue is that I can't install or have anything installed on this vax. I have to use what is already installed...
our vax administrator doesn't really know anything beyond the programs that we use that were written in the 70s and 80s and none of the source code is there. Oh wait, she knows how to shuffle data around so the drives don't get full.... lol
also, does anyone know how to set the prompt to show the current directory (much like prompt $p$g in DOS?) She has it set that way on her terminal, but can't figure out how to set it that way on mine...

PrinceAlexi,
Setting the prompt is straightforward, the command is SET PROMPT. The string to be used is the parameter. You get the current directory using the F$ENVIRONMENT lexical function.
Information on both of these is in the HELP text, use the HELP command (for example, HELP SET PROMPT) to get details.
Electronic copies of most of the manuals for OpenVMS and its layered products can be reached through the HP www site at http://h71000.www7.hp.com/doc/
On the subject of graphics, there is full support for Xwindows, but you need to be running a MOTIF-based client, presuming that the Xwindows support is enabled.
Can you be more specific about what you are trying to do, at least what type of graphics support that you need on what device?

I believe what he is looking for is a Fortran library similar to Qt for KDE. Some library that will allow you to generate "dialog" boxes and manipulate them.
Which, I believe that the only real choice is Motif - because it's already there. He may want to search for information on Xlib and Fortran. I'm confident that it would be easier to program the gui in C and just compile your fortran code to .OBJ and link them.
If anyone else has more information... I also like to know.
