Defining rule or pattern dimensions

cipointsto the dot. It roundsup fractionsto the next integer. So 1225
decipointswouldworkoutto510.4dots,andthepnntcrroundsthisupto511

Horizontally,youcan specifythe rule lengthor horizontalpatternsize in
dotswiththiscommand:

Alternatively,to specifythe horizontaldimensionfor a rule or pattcm in
decipoints,youcan printthiscommand:
<ESC>
*C n H
in whichn is thehorizontalrule,or patternsizein decipoints.
Vertically,youcanindicatethesizeof yourruleor patternindotswiththis
