Macro: replace order bug(?)

See original GitHub issue

There some problem that short variables can to brake more long variables:

#def MACRO1$(Dx$; x$)
    x$ + Dx$
#end def
#def MACRO2$(x$; Dx$)
    x$ + Dx$
#end def

MACRO1$(10; 20)'shows 20+10=30
MACRO2$(10; 20)'Error in "10 + D10" on line [2]: Undefined variable or units: "D10".

I’m not shure is it bug or not, but can we replace variables from long to short order?

Yes, It is a bug. Variables are parsed from longer to shorter. But for replacement, I simply used the string.Replace() method in C#, cycling through the parameter in their original order. The best way is to write custom replace method that does the job in just one pass, but it will take time.

Now, I can make a quick fix by preliminary sorting the parameters by their length - from longer to shorter and perform the replacement in this order.

Thanks! It works correctly now (so big problems not found at least)
