Not as good as being able to use Find and Replace directly, admittedly, but not a big hassle, especially as it's not something that is likely to be done very often. I'd say this is low priority for Prime - there are many more important items that need fixing. Alan |
Alan,
I'm sure you're right when you say there are other things that need fixing first (I don't have Prime 2), but I have a long-standing request to improve Mathcad's Find and Replace facilty to be something far more practical. A user should be able to type an expression into the find & replace boxes in the same way that they enter expressions in a worksheet and to replace expressions. This goes for not just Valery's example, but also for more complex expressions and changing the Math Style of a name.
I've also asked for the ability to delay evaluation of an expression, which might have made the use of substitute a bit easier.

I think it might be possible to meet Valery's need by using a component that modifies the XML of an expression ... not a simple task, but I think it could be done. It would probably mean tagging expressions that either need changing or shouldn't be changed. Possibly, a listbox could populate itself with a list of all instances of the desired variable / term, allowing the user to select/de-select instances for replacement. I haven't tried it; something for the Scripting and XML Experts, I think.
