Thank you for your comprehensive reply. I will try to follow your examples in the environment you mention once I have created it.

I tried Q_ERR_ON and on my setup this did not seem to work with EVAL.

I have been struggling recently with a program I am trying to write using the instructions EVAL and COMPIL$. My problem lies with the fact that this combination within QPC2 and Qlib fails when a non arithmetic string is passed to it. Now you may ask why one would to do this and the answer to that, i...

Thank you for your recent replies. I have decided to download all of QBITS' programs and documents to see what I can learn from them. As everyone agrees the pdf documentation is first class. What programs were used to create the documents? I can understand Derek's post (just). Am I right in thinking...

I agree with the comments made by derek_stewart:- I really like the QBITS manuals. stevepoole:- Your program looks great. bwinkel67:- All these programs seem really neat. My problem is that I can't get them to run well (or even at all) on my SMSQE configuration. I have a question:- Where is the file...
