Subject: (math-grade-vec): New variable.
X-Git-Tag: ttn-vms-21-2-B4~3638
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=866ebaa9050adcc75b2c6f057b35266dafce41b4;p=emacs.git

(math-grade-vec): New variable.
(calcFunc-grade, calcFunc-rgrade, math-grade-beforep): Replace
variable grade-vec by declared variable.
(math-rb-close): New variable.
(math-read-brackets, math-read-vector): Replace variable close by
declared variable.
