i want to convert Hex value To EBCDIC value.
i tried to convert hex to ascii and then to ebcdic but it doesn't give desired results .

it doesn't give corresponding ebcdic value instead it gives some junk values.
e.g;
Hex EBCDIC
-----------------
81 a
82 b
83 c
84 d
85 e
86 f
87 g
88 h
89 i


Hex EBCDIC
-----------------
C1 A
C2 B
C3 C
C4 D
C5 E
C6 F
C7 G
C8 H
C9 I


code is as:

I was even surprised your code compiled.

thanks for your attention
But for
char hexval[10]="c1c2c3c4c5";
i am expecting EBCDIC values as:
A
B
C
D
E
but i am getting
ascii value is 193 Á
ebcdic value is 119
ascii value is 194 Â
ebcdic value is 120
ascii value is 195 Ã
ebcdic value is 128
ascii value is 196 Ä
ebcdic value is 138
ascii value is 197 Å
ebcdic value is 139



how can i get the values as A B C D E.......

Why are you expecting 0xC1 to display A ?
0xC1 in "ASCII" (actually ISO-LATIN1) is Á.

Why are you expecting 0xC1 to display A ?
0xC1 in "ASCII" (actually ISO-LATIN1) is Á.
*********************************
the ebcdic equivalent of 0xc1 is A
and i have to print EBCDIC equivalent Not Ascii equivalent


i changed following array

and printed outarr as character
i am getting correct values for alphabets
but not for numerals

For 0XC1 EBCDIC Value is A
hence at position 193 of array i have put value = 65
as 0X65 in ascii is A


it works for alphabets

Your code is using 0xC1 as an ASCII value, not an EBCDIC one.
