* revised for TMAP
* from PPLUS :
*	Directory PMEL:[PLOT5.PPLV11.PLOT]MINMAX.FOR

* search for "TMAP" to find all revisions
* *sh* - 1/27/89 corrected bug: min/max search improperly rejects LIMITs points
* *sh* - 12/8/93 corrected bug: vectors blow on divied by zero attempt
* *jd* - 4.20.99 Don't delete symbols {X,Y}{MIN,MAX} in overlay plots
* V686 *acm* 11/13 Allow symbol names to be up to 120 characters long
