Lossless Assignments
A lossless assignment is an assignment between incompatible data types in which the conversion is checked to see whether data is lost. Lossless assignments can be performed using the

lossless operator EXACT , in which the argument is converted to a result of the specified type using the

rules for lossless assignments.

This makes it possible to use lossless assignments in all operand positions in which EXACT
can be specified.
The real meaning of a lossless assignment is the following method of using a constructor expression
with EXACT as the right side of an assignment :

Syntax
destination = EXACT #( source ).
In this case, source is converted to the data type of
destination and checked accordingly.

Notes

If the argument of the operator

EXACT is an arithmetic expression , a lossless calculation is performed instead of a lossless assignment.

Using the addition EXACT in the obsolete statement MOVE is an obsolete form of lossless assignment.
