DCL:GRPH2:UBPACK: Labeled Polyline Routines

13.1 Summary

The UBPACK is a subroutine package for drawing labeled polylines.

The functions that were realized in this package have been realized by the polyline primitive in GRPH1, and so this package will be deleted in the future.

Only a list of the subroutines will be given here. The names of the corresponding routines in the GRPH1/SGPACK are given in parentheses.

UBPLZU (sgplzu)	Draws a labeled polyline in UC. (Also sets attributes.)
UBPLZV (sgplzv)	Draws a labeled polyline in VC. (Also sets attributes.)
UBPLU (sgplu)	Draws a labeled polyline in UC.
UBPLV (sgplv)	Draws a labeled polyline in VC.
UBSPLT/UBQPLT(sgsplt/sgqplt)	Changes/inquires the line type.
UBSPLI/UBQPLI(sgspli/sgqpli)	Changes/inquires the line index.
UBSPLC/UBQPLC(sgsplc/sgqplc)	Changes/inquires the text for the label.
UBSPLS/UBQPLS(sgspls/sgqpls)	Changes/inquires the height of text.
UBPGET/UBPSET(sgpget/sgpset)	Inquires/changes an internal variable.

The following are the differences between the polyline primitive in the UBPACK and the SGPACK.

• ubplu and ubplv are set every time they are called. The character number of the last character in the text was increased by one, but sgplu and sgplv do not change the set text. However, when the routine sgmplc is called, the character number of the last character in the text is increased.
• The internal variable 'INDEX'  handled by ubpget/ubpset is handled as 'INDEXC' by sgpget/sgpset.
