9.23. Replacement Characters

Earlier versions of VHDL allowed certain characters in models to be replaced with others. Specifically,

A vertical bar ("I") could be replaced by an exclamation mark ("I")
The number-sign characters ("#") in a based numeric literal could be replaced by colon characters (":").
The double-quote characters ("″") in a string literal could be replaced by percent characters ("%I").
