I know that this is more of a DOS issue than an HP calc issue, but it is driving me squirrelly.
I have begun to use the admittedly ancient DOS-based HP48 PDL as I work up some simple User RPL programs.
I like how the interface works on my one computer--though it is DOS based the editor works well and the special symbols can be inserted into code by point and click.
The problem is on my other computer. When I run the program in a DOS command window, the special symbols are not correctly rendered in the menu bar, but are replaced with weird ascii equivalents. For example "less than or equal" is rendered by 3/4 (in small font), the squareroot symbol is rendered by something else, and several of the greek letters are rendered by something inscrutable.
But here is the trick. I hit Alt-Enter to go into fullscreen dos mode. From the File menu I choose "Exit to DOS". At the DOS prompt, I type Exit and revert to the PDL IDE and, voila, the symbols are properly represented. However, if I hit Alt-Enter again and go back to a DOS window, the proper representation is lost and I have to start all over again with the above workaround to get the symbols back.
I like to use this in a DOS window rather than fullscreen mode, and the symbols are properly represented on my one computer without difficulty. Are there some system parameters or paths I should be altering to make sure the required font, which evidently is on the computer somewhere, is found when I start up PDL in a DOS window.
This is largely an aesthetic thing, I know, but I really like things to work, and get mystified when then work on one system but not another.
many thanks,
Les
