Description
The SET() function returns ON or OFF depending on the status of the system setting. The character expression <expC> is the SET command keyword. This function can also be used in conjunction with the SET command to toggle the various SET COMMANDS ON and OFF.
If the optional <expN> is included and is greater than zero (0), additional information is returned for those set commands that have more than one setting. For example, the SET ALTERNATE command has two settings: SET ALTERNATE ON/OFF and SET ALTERNATE TO <filename>.
Example
? set("safety") OFF // Another Example // toggle exclusive to the opposite setting set exclusive(iif(set("exclusive")="ON",.F.,.T.))
