Hackers Guide to Visual FoxPro 7.0

Set Headings, Set("Headings")

This is a schizophrenic command that controls two similar, but unrelated, things. SET HEADINGS determines whether column headings appear in the output of commands that list fields. It also determines whether TYPEing a file includes the name of the file and the date. Why are these things linked together? Who knows?

Usage

SET HEADINGS ON | OFF cCurrentHeadings = SET("HEADINGS")

In its first incarnation (column headings for listing commands), SET HEADINGS affects DISPLAY, LIST, AVERAGE, CALCULATE and SUM.

Example

cOldHead=SET("HEADINGS") SET HEADINGS OFF USE Employee * Rough average age AVERAGE YEAR(DATE())-YEAR(Birth_Date) FOR NOT EMPTY(Birth_Date) SET HEADINGS &cOldHead
