Fileoutput in programs? 2

[ChrMeissner]

Hi all,

I have a very big program/procedure in 'MathCad 2001 Pro' that takes more than one hour for calculation. Sometimes it never comes to an end.

How can I put an interim result to a file while the program is running? ('PRNSCHREIBEN' doesnt work in programs)

If that would be possible, I would be able to look in this file with an editor and know how far the calculation already is and why it doesn't converge.

Many thanks,
Christian (TU Chemnitz, Germany).

There is an undocumented 'feature' in MathCad which allows you to write data out to a file from a program. Looks something like

writeprn(myvariable, "myfilepath")

Where myvariable is the variable or matrix to be written out, "myfilepath" is a string containing the complete path to your file.

Now I have looked at it I am not sure whether myvariable and "Myfilepath" should be the other way round - experiment.

Many thanks for this helpful hint. I just wrote a litle C-Program for overseeing the status of a MathCad procedure. It's fantastic!

Here is a screenshot:

Bye,

Good one, TheWordforToffee! I've always wanted a way of getting intermediate results for debugging purposes, and this does nicely.

The actual syntax is WRITEPRN(filename,A) or APPENDPRN(filename,A).
