Is there anyway to write a program filled with functions, then write another program that utilizes them. I have tried one way but i might be doing it wrong.

If you want a program that uses lots of subfunctions, I suggest declaring the functions as local variables and then defining them using Define f(x,y)=Func. For example:

myprgm()
Prgm
Local f,g
Define f(x)=x^2
Define g(x)=Func
If x=0:Return true
Return x>5
EndFunc

Disp g(f(5))
EndPrgm


You can use subprograms in the same way.

The one drawback of this method is that I don't think the local functions/programs will be able to call each other. To get around this, you could declare them as global variables, then delete them when you're done. Be sure to be in a different folder when you declare global variables, though, rather than overwrite the user's variables.

Yeah but if i had that program and then created one that looked like

myprgm2()
Prgm
myprgm().f(x0
EndPrgm

i cant get it to work. How would i call the function in myprgm() from myprgm2()?

Read the second part of my post. You'll need to declare f() as global. Then, just call it with f(x).
