Controls use of dollar signs ($) in identifiers.
#pragma dollar_identifiers on | off | reset
If you enable this pragma, the compiler accepts dollar signs ( $) in identifiers. Otherwise, the compiler issues an error if it encounters anything other than underscores, alphabetic, numeric character, and universal characters ( \uxxxx, \Uxxxxxxxx) in an identifier.
This pragma does not correspond to any panel setting. By default, this pragma is off.
