Compiler hints are generated by the macro compiler to draw attention to unused code, obsolete function calls, or result variables that have not been assigned a value. They do not prevent compilation of the macro, but may reveal an unintended omission.

 

This can either result in an inefficient (slow) macro, or could be the sign that there is a logical bug in your macro.

 

The causes for this can be diverse:

 

•A variable is declared but never used.

•A value assigned to a variable is never used.

•An essential system variable, such as sRESULT and bRESULT, is not used anywhere in the macro.

 

Hint messages from the compiler are not fatal.
