In an internationalized environment, it is often necessary to convert data from one code set to another. The following converter subroutines are supported for this purpose:
| iconv_open | Performs the initialization required to convert characters from the code set specified by the FromCode parameter to the code set specified by the ToCode parameter. | 
| iconv | Invokes the converter function using the descriptor obtained from the iconv_open subroutine. | 
| iconv_close | Closes the conversion descriptor specified by the cd variable and makes it usable again. | 
| ccsidtocs | Returns the code-set name of the corresponding coded character set IDs (CCSID). | 
| cstoccsid | Returns the CCSID of the corresponding code-set name. |
