This compiler error is similar to the duplicate variable message, but will occur only if, in a user-defined function, you have a variable name which is already declared in either of the global, input, or var sections of the macro's main body.

For example:

function MyFunction(nSomeDate): s
var
   nRunDate  // variable already declared in var section below
begin
   return 'OK'
end
 
var
   nRunDate
begin
   // error generated even if the function is never called
end

This error message will be generated even if the user-defined function referred to is never used anywhere in the macro.

See also: variable is used in one or more function prototypes.
