unsigned char EBCDICtoASCII(const unsigned char c)

****************************************************************

you have to creatr a file a2e.h & save it in INCLUDE folder of your C Installed Directory.

Now Code for Header file a2e.h

#ifndef A2E__H
#define A2E__H

unsigned char ASCIItoEBCDIC(const unsigned char c);   /* A2E.C          */
unsigned char EBCDICtoASCII(const unsigned char c);   /* A2E.C          */

extern int ascii2ebcdic[256];                         /* Toascii.C      */
extern int ebcdic2ascii[256];                         /* Toascii.C      */

#endif /* A2E__H */
