idlwave-toggle-comment-region

idlwave-toggle-comment-region is an interactive compiled Lisp function in `idlwave.el'.


(idlwave-toggle-comment-region BEG END &optional N)

Comment the lines in the region if the first non-blank line is
commented, and conversely, uncomment region. If optional prefix arg
N is non-nil, then for N positive, add N comment delimiters or for N
negative, remove N comment delimiters.
Uses `comment-region' which does not place comment delimiters on
blank lines.
