I see. I must put the single quote around te f, not the f(j). Makes perfect sense.

Thank you!

Hi,

Thank you for your answer. I now know one more way-using :- instead of brackets.
I gleen from your comments that the differences are meaningful when doing much more complicated things than the things I do.  I am pretty ignorant about CS lingo but I can and do use maple constantly. It sounds like I can remaon ignorant and just use the long form of the command and be safe so that is what I will do.

You mention your peference for packagename:-packageexport. How does one know if a package is a module? Trial and error?

Thank you, I can do that. I lose that elegant italic font that math mode uses but I no longer have bold for, or , and next, etc words. Most important, Maple does not try to execute when I hit return.

Good suggestion. Thank you.

But the command

solve({eq3,eq5},{d,s})
as per PatrickT 1798 's xhggestion does give the right answer.

That is a strange phrase to return from a procedure. I suspect I have a problem using assign inside a procedure and will try to figure out what is wrong but can the Typesetting:-mfenced  output give me a hint?  I do not know what Tppe MK commads are.

thanks,
