FUNCTION:
_IsDBF( cFileName ) --> lIsDBF
PARAMETERS:
cFileName : The name of the file to check
SHORT:
Determine if a file is a dBASE III+ compatible database file.
DESCRIPTION:
_IsDBF() returns TRUE if cFileName has a 03h or 83h in the first byte
(indicating a POSSIBLE dBase III+ database)
NOTE:
Just because a file DOES have an 03h or 83h in the first byte does not
necessarily mean that the file actually IS a dBASE database. Use judgement
when using this function.
See also _IsDBFMem() which returns information regarding the presence of
MEMO fields in a database.
EXAMPLE:
t = _IsDBF('TEST.DBF')
Result: t = TRUE
