The $TYPE function returns a value that indicates the data type of a variable.

variable

is the identifier of a simple variable, array, simple pointer, structure, structure data

item, or structure pointer.

Usage Considerations

For a structure pointer, $TYPE returns the value 8, regardless of whether the structure

pointer points to a structure or to a substructure.

You can use $TYPE in LITERAL expressions and global initializations, because

$TYPE always returns a constant value.

Example of $TYPE Function

In this example, $TYPE returns the data type of a REAL(64) variable:

REAL(64) var1; !Declare variables

INT type1;

type1 := $TYPE (var1); !Return 6 for REAL(64)
