*
*
* Modified PPLMOD_PLTIT and PPLMOD_PLOTXY to execute the ALINE command
* where a line is drawn of a particular type as specified.
* J Davison 10.4.89
* v5.5 *acm* 12/02 For dot plots -- plot a symbol in the middle as well.
* Taken from aline_sub, but put a third symbol in
* the middle of the line the key of a line-plot
* V73 3/18 *kms* For clarity, append MD to makedot.cmn values IPT, XDOT,
* and YDOT; make MDOT (99) a makedot.cmn parameter DOTSYMIM
