= as String End ??

[ashu]

I am trying to highligt only the
CAPACITY= in the expression
CAPACITY=0.42993 BTU/Lbm-F

However the text pad highlights the whole string rather than just CAPACITY= as defined in the keyword definition.

[Syntax]
Namespace1 = 6
IgnoreCase = Yes
InitKeyWordChars = A-Za-z
KeyWordChars = A-Za-z0-9,=_
BracketChars = []
OperatorChars = +-/=<>;%&
PreprocStart =
CommentStart =
CommentEnd =
CommentStartAlt = "
CommentEndAlt = "
SingleComment = !
SingleCommentCol =
SingleCommentAlt =
SingleCommentColAlt =
SingleCommentEsc =
SyntaxStart =
SyntaxEnd =
StringStart = '
StringEnd = '
StringAlt = "
StringEsc = '
CharStart = '
CharEnd =
CharEsc = '

Could someone help to figure out how to make texpad identify = as a StringEnd
