PLEASE SCROLL TO THE END OF THIS THREAD, the most recent version is there. Thanks,

Eddie

Code:
EXPORT COORDCONV() BEGIN // 2014-02-03 EWS // Source: CRC LOCAL ch,X,Y,Z,R; LOCAL θ,ρ,φ; CHOOSE(ch,"Coord. Conv.","Cart→Cyl", "Cyl→Cart","Cyl→Sph","Sph→Cyl", "Cart→Sph","Sph→Cart"); CASE IF ch==1 THEN  INPUT({X,Y,Z}); RETURN [√(X²+Y²),ARG(X+Y*√(-1)),Z];  END; IF ch==2 THEN  INPUT({R,θ,Z}); RETURN [R*COS(θ),R*SIN(θ),Z]; END; IF ch==3 THEN INPUT({R,θ,Z}); RETURN [√(R²+Z²),ARG(Z+R*√(-1)),θ]; END; IF ch==4 THEN INPUT({ρ,φ,θ}); RETURN [ρ*SIN(φ),θ,ρ*COS(φ)]; END; IF ch==5 THEN INPUT({X,Y,Z}); RETURN [√(X²+Y²+Z²), ARG(Z+√(-1)*√(X²+Y²)),ARG(X+√(-1)*Y)]; END; IF ch==6 THEN INPUT({ρ,θ,φ}); RETURN [ρ*COS(θ)*SIN(φ),ρ*SIN(θ)*SIN(φ), ρ*COS(θ)]; END; DEFAULT RETURN "CANCELLED"; END; END;

Note: Sqrt(-1) is that "I" character (Shift+3).
