2001/10/02 PA - Plot absolute PA [ X, Y [,...]] [;] X ; X coordinate of the cursor movement destination Y ; Y coordinate of the cursor movement destination • Coordinates are absolute values in user or current units. • Whether used with or without parameters the command establishes absolute plotting as the plotting mode. • The command moves the cursor to the specified coordinates, drawing straight lines, only when the pen is down. • In symbol mode PA draws the specified symbol at each point in the parameter list. • In polygon mode the specified coordinate pairs are placed in the polygon buffer. • If an odd number of coordinates are specified, the final (unpaired) coordinate is ignored. 10 ' -- Plot Absolute -20 WIDTH "LPT1:",255 30 LPRINT CHR$(27);"E"; 40 LPRINT CHR$(27);"%0B"; 50 LPRINT "IN;SP1;"; 60 LPRINT "PA2000,6000;PD0,6000,2000,7500,2000,6000;PU2500,6000;"; 70 LPRINT "PAPD4500,6000,2500,7500,2500,6000;PU10365,500;"; 80 LPRINT CHR$(27);"%0A"; 90 LPRINT CHR$(27);"E"; 100 END PR - Relative coordinate pen move PR [X, Y [,...]] [;] X ; X coordinate of the cursor movement destination Y ; Y coordinate of the cursor movement destination • Coordinates used are relative values in current units. • Whether used with or without parameters the command establishes relative plotting as the plotting mode. • The command moves the cursor to the specified coordinates, drawing straight lines, only when the pen is down. • You can specify any number of coordinated pairs and plotting is performed in the order the coordinates are specified. • In symbol mode PR draws the specified symbol at each point in the parameter list. • In polygon mode the specified coordinate pairs are placed in the polygon buffer. • If an odd number of coordinates are specified, the final (unpaired) coordinate is ignored. 10 ' - Plot Relative 20 WIDTH "LPT1:", 255 20 LPRINT CHR$(27); "E"; 30 LPRINT CHR$(27); "%0B"; 40 LPRINT "IN;SP1;" 50 LPRINT "PA5000,4500,;PDPR-2000,0,2000,2000,0,-2000;PU500,0;" 60 LPRINT "PD2000,0,-2000,2000,0,-2000;PU;" 70 LPRINT CHR$(27); "%0A"; 80 LPRINT CHR$(27); "E"; 90 END CHAPTER 4 HP-GL/2 - 19
