isebcdic -- EBCDIC Character Test

SYNOPSIS

 #include <lctype.h>

 int isebcdic(int c);

DESCRIPTION

isebcdic tests an integer value c to determine whether it is a character belonging to the EBCDIC character set.

RETURN VALUE

isebcdic returns 0 if the integer is not an EBCDIC character (that is, if it is not between 0 and 255). If c is an EBCDIC character, isebcdic returns a nonzero value.

CAUTION

Do not assume that isebcdic returns either 0 or 1.

PORTABILITY

isebcdic was devised as a replacement for the isascii function in an EBCDIC environment. See isascii for further information.

EXAMPLE

This example tests for printable EBCDIC characters:

  #include <lctype.h>
  #include <stdio.h>

  void main(void)
     {
     int count;
     int candidate;

     for (count = 0; count < 50; count++) {
        candidate = rand() / 32;
        printf("%d %s to the EBCDIC character setn", candidate,
           isebcdic(candidate) ? "belongs" : "does not belong");
        }
     }
