Correlative and Conversion Codes

conversion codes

This appendix describes the correlative and conversion codes used in dictionary entries and with the ICONV, ICONVS, OCONV, and OCONVS functions in BASIC. Use conversion codes with the ICONV function when converting data to internal storage format and with the OCONV function when converting data from its internal representation to an external output format. Read this entire appendix and both the ICONV function and OCONV function sections before attempting to perform internal or external data conversion.

Note: If you try to convert the null value, null is returned and the STATUS function returns 1 (invalid data).

The NLS extended syntax is supported only for Release 9.4.1 and above.

The following table lists correlative and conversion codes.
