$HINT | $HINTS | $H - Define compiler hints behavior

hints-directive = ( $HINT | $HINTS | $H ) [ hint-reference ] directive-toggle { "," hint-reference directive-toggle } .
hint-reference = hint-number | hint-identifier .

Define compiler's hints behavior.

NEW! (V2.1): Several hints may be changed in the same directive, separated by commas. Nevertheless a global hints on / off cannot be mixed with individual hint on / off in the same directive.

<hint-number>:

Validate or invalidate only the specified compiler hint by its number after this point.

<hint-identifier>:

NEW! (V2.1): Validate or invalidate only the specified compiler hint by its identifier after this point. Not all hints have an equivalent identifier, see below.

<directive-toggle>:

ON / OFF or "+" / "-": if <hint-reference> is omitted, validate or invalidate all the compiler hints after this point of source code, overriding the default option defined in the Project's Options; else validate or invalidate only the <hint-reference> hint.

• Validating or invalidating all hints does not reset any individual hint off state.
• Hint numbers will not change with PMP's version. Suppressed hints are marked as "reserved" and become placeholders for new hints.

{$H 2-} // Do not report RMW potential problems
{$HINT UNUSED_SYMBOL OFF} // Do not report unused symbols
{$HINT DEPRECATED OFF, RMW ON}

Hint numbers vs their identifiers vs their text:

• In texts above "%s" is a placeholder for additional information.
