C-ISAM can store data on disk in several ways; any of these can be read from or written to using a PROIV application. The C-ISAM data types and the corresponding entries at the PROIV file definition field External Type is as follows:

C-ISAM Type	PROIV Type	Comments
CHAR	ALPHA	ASCII character data
INT	PCOMP1	Two-byte integer
LONG	PCOMP2	Four-byte integer
DECIMAL	C-DEC	Decimal Format, storage format required
FLOAT	C-FLT	Single Precision floating point
DOUBLE	C-DBL	Double Precision floating point

C-ISAM Data Types and PROIV

All other PROIV external types can be used with C-ISAM files, but non-PROIV applications may need additional programming to convert them.
