I didn't understand what you talking about. Please take a look: http://smath.info/live/?file=122 - here you can see that no problem to work with variables after function.
Please make an example.

Calculation work properly, but i wil change [MATH]Y(R;X)←sqrt(R^2+X^2)[/MATH] to [MATH]Z(R;X)←sqrt(R^2+X^2)[/MATH]. I canot change variable name Y to any new variable name, for example Z. I have to delete whole expression and then type new one.

Oh, I see. Today a new release will be available. Then I will try to implement function name changing ability. Thank you.

Hi all,
Smath is great program, my compliment. But thre are some next problems with editing expresion. For example:
[MATH]a←2[/MATH] [MATH]b←4[/MATH][MATH]d←5[/MATH][MATH]c←1[/MATH]
[MATH]2*(a+b)+3*(c+d)=30[/MATH]
I will change expresion to become [MATH](a+b)+3*(c+d)=24[/MATH]. Its unposible delete number 2.
How can I delete first parenthesis in [MATH](a+b)+3*(c+d)=24[/MATH] to become [MATH]a+b+3*(c+d)=24[/MATH].
A key DELETE on some places does not work.
God luck by debuging.

Hello, Stanley.

Yeah, it's true. DELETE keyboard button doesn't work into math expressions. Hope, this will be fixed into our next release.
