Description

If SET HEADING is ON, then column titles will be displayed for the DISPLAY, LIST, SUM and AVERAGE commands. If SET HEADING is OFF, then no column titles will be displayed. If SET DESCRIPTIONS is ON, then the field description is displayed as the column title in place of the field name. By default, HEADING is ON.

The SET HEADING TO command controls the underlining of column headings in output files. The SINGLE or DOUBLE options will generate SINGLE or DOUBLE underlining on column headings. If NONE is specified then no underlining is generated for the column headings. When used in conjunction with the LIST | DISPLAY ... TO FILE, SET DESCRIPTIONs, SET PAGEWIDTH and SET PAGELENGTH commands, SET HEADING provides the ability to produce ad-hoc reports. The default for SET HEADING is NONE.
