Setting a pattern table, using call CHPAT

In addition to the three attribute tables mentioned in the line graph section (line types, markers, and colors), it is possible to set a pattern table:


     DCL PATTERNS(4) FIXED BIN(31) INIT(14,8,5,12);
                                                /* Patterns in table */

     CALL CHPAT(4,PATTERNS);            /* Establish a pattern table */

If system patterns are being used, the pattern numbers must lie in the range 0-16. If a user pattern set has been loaded (using the GSLSS or PSLSS call), then patterns in the range 65-254 can be used also.
