C_GETVAR()
DESCRIPTION
C_GETVAR() returns the contents of the currently active GET during
a Clipper READ command.
NOTES
The C_GETVAR() function returns the contents of the active GET
variable as opposed to Clipper's READVAR() function which returns
the name of the active GET variable.
C_GETVAR() is most useful during a VALID function or a SET KEY
procedure to report the contents of the GET variable.
SYNTAX
C_GETVAR()
PARAMETERS
There are no parameters.
RETURNS
C_GETVAR() returns the contents of the currently active GET for
whatever data type was specified when the GET was initialized. If
the GET variable is empty, the empty values for the particular data
type are returned.
EXAMPLES
mname = space(15)
maddr = space(25)
mcity = space(12)
@ 0,0 get mname valid ck_name()
@ 1,0 get maddr
@ 2,0 get mcity
