The procedure idlv4_to_v5.pro in
http://idlastro.gsfc.nasa.gov/ftp/contrib/landsman/v5
(and supporting procedures (FDECOMP, MATCH, REMOVE, ISFUNCTION() )
is about 98% efficient in converting all indexing parentheses into
square brackets. It has occasional problems with continuation lines, and
indicies within strings (e.g. for an EXECUTE() statement).
