how to find out who causes an error

Hi,I use the error message function to inform me about some errors in a few functions. At the same time I use on error operator to get already calculated results in a loop. Without it I can't see what is happening (I can't get already calculated results).

I want to find out which function causes an error without using debug mode. Is it possible?

Simplified example without loop is attached.

I guess you'll have to ask in func3 multiple times

Another option might be that func1 and func2 don't throw an error but return some kind of error code as reault which then can be checked by func3.

Thank you very much for idea to return error code (string) instead of firing an error. It works well enough.

Mathcad 15 has a trace command.  This will provide output during the running of a program.  It is helpful in debugging programs.  Prime 6 does not have the command.

 

Cheers,

Thanks David, but debug mode doesn't give you ability to see long vector or matrix, it does't give you ability to plot already calculated results. If MC meets error it doesn't return anything. That's why I wrote "not using debug mode".
