CopyVar CATALOG
CopyVar var1 , var2
Copies the contents of variable var1 to var2. If var2
does not exist, CopyVar creates it.
Note:
CopyVar is similar to the store instruction
(! ) when you are copying an expression, list,
matrix, or character string except that no
simplification takes place when using
CopyVar.
You must use
CopyVar with non-algebraic
variable types such as Pic and GDB variables.

cos(
expression1 ) returns the cosine of the
argument as an expression.
cos( list1 ) returns a list of the cosines of all
elements in
list1 .
Note: The result is returned as a degree, gradian
or radian angle, according to the current angle
mode setting.
In Degree angle mode:
