Threaded Mode | Linear Mode

I wrote the program for the cas mode.

Code:

#cas

zf74(X,Y,γ,a,b):=

BEGIN

LOCAL f,v;

PRINT("---------------------------------");

PRINT("W#7, P#4:");

γ:=unapply(γ,x);

X:=unapply(X,{x,y});

Y:=unapply(Y,{x,y});

f:=expand(simplify(subst(X(x,y)+Y(x,y)*diff(γ(x),x),y=γ(x))));

PRINT("f(x)="+f+";");

PRINT("F(x)="+expand(simplify(∫(f,x)))+";");

v:=∫(f,x,a[1],b[1]);

PRINT(suppress("∫(f(x)"," ")+", x, "+a[1]+", "+b[1]+")="+v+when(FP(v)≠0,"="+ROUND(v,4),"")+";");

PRINT("---------------------------------");

1;

END;

#end

After a lot of runs in the CAS Vars menu the garbage or/and empty-names variables appear. This issue happens while running my other cas programs.
