How to pass variable name to function in program

[XcasEngGuy]

I am trying to pass a variable name into a function to include in a command. I want a function that can, for example:

eq=3*x^2+x
int_test(eq,x)

such that it can integrate the equation stored in eq by x. yielding:

int(3*x^2+x,x)

i can't get it to stop doing this:

int(3^x^2+x,<the variable name in the program>)

I'm confused. Perhaps you just need to quote the variable name '('x' instead of x)?

I discovered:

eq:=-1/18*L^2*w+5/9*L*w*x-1/2*w*x^2
ind_var:=x
eval(expr(int,eq,ind_var))

works
