The label() routine in /usr/lib/lib4014.a is badly broken in UNIX System V Release 2. The incremental plot mode offset makes very little sense since it cannot restore the initial location before the character is plotted, it makes even less sense when several characters are in the label, and terminals such as the Tektronix 4105 do not understand the incremental plot codes. To make matters worse, the label() routines forgets to forget its current location (oloy, ohix, ohiy, oextra should be reset to -1), so future vector instructions may output incorrect short co"ordinate sequences. Source for the broken module is something like /usr/src/lib/libplot/t4014/label.c . Affected utilities include tplot (via /usr/lib/t4014) and lots of stuff in PWB/Graphics. Grrr.
