Vector table directives specify how the YDSPHLP program should translate an area of the display into a label; if the cursor location is within the area, the specified label will be used to position the display. They are only required if cursor-sensitive help text is to be used. At run time you will need to supply values for the CSRLOC and optionally for the LBLGRP parameter on the YDSPHLP command.
Enter vector table entries exactly as shown:
Label group: up to three separate label groups (a label-group is one character long) may be specified, each preceded by a space or an ‘N’. Label groups allow you to display different parts of the same text member under different circumstances. Any alphabetic or numeric character may be used to identify a label group. The YDSPHLP program will compare these label groups with those supplied at run time by the LBLGRP parameter, if any, to decide whether a particular vector table entry is eligible for use or is to be ignored (see the following section on conditioned help text).
Row coordinates: must be between 1 and 24; leading zeroes may be entered as blanks.
Column coordinate: must be between 1 and 132; leading zeroes may be entered as blanks.
Label name: must refer to the label specified on a *YH: directive placed in the body of the help text. You may also specify the same label on an index entry directive (*YI:), though this is optional. Any text in columns 36-80 following a label name will be ignored.
