_a2e_n, _e2a_n - Convert from ASCII to EBCDIC and EBCDIC to ASCII

Definition	#include <ascii_ebcdic.h> char*_a2e_n (char* z, size_t n); char*_e2a_n (char* z, size_t n); The functions _a2e_n and _e2a_n convert the string z passed as a parameter with a length of n from ASCII to EBCDIC or vice versa. Conversion takes place on the spot. The corresponding data areas thus have to be writable. The conversion tables are declared as follows: unsigned char _a2e_tab[256]; unsigned char _e2a_tab[256];
Parameters	char* z String in ASCII or EBCDIC encoding to be converted size_t n Number of characters to be converted in the string z
Return val.	The string z passed as a parameter, after its conversion to EBCDIC or ASCII
Note	These functions are suitable for processing character arrays containing the null byte (\0), since they do not interpret the null byte as the ’end of text’.
