I'd like to express an angle in DCAL, but am not sure how to do it.
What I am wanting to do is get something to use for sin (angle).
Thanks much,

All of dcal trig routines use radians.
If you have used the procedure 'getang' to obtain the angle from the user via the standard dataCAD menu then the angle obtained will be in radians. If you are inputting them via program in degrees you will need to convert the angle to radians.
adeg: real
Arad: real
Arad:=radians(adeg);
