Calling a Function

Functions return a value. You can display, capture, or use the return value, depending on how you call it.

To call a function

• Use the = (equal) operator, followed by the function name and parentheses that contain any parameters you pass to the function.

  =cMyUDF()
  =cMyUDF(p1,p2)
  

• You can also omit the = (equal) operator. For example,

  cMyUDF()
  cMyUDF(p1,p2)
  

In other words, = is optional.

You should avoid using a ? before a function call because ? will send output to the screen.

If you omit the RETURN statement in a UDF, the default return value is true (.T.).
