ordchr(3am)


NAME

   ordchr - convert characters to strings and vice versa

SYNOPSIS

   @load "ordchr"

   number = ord("A")
   string = chr(65)

DESCRIPTION

   The  ordchr  extension  adds  two functions named ord().  and chr(), as
   follows.

   ord()  This function takes a string argument, and returns  the  numeric
          value of the first character in the string.

   chr()  This  function  takes  a  numeric  argument and returns a string
          whose first character is that represented by the number.

   These functions are inspired by the Pascal language  functions  of  the
   same name.

EXAMPLE

   @load "ordchr"
   ...
   printf("The numeric value of 'A' is %d\n", ord("A"))
   printf("The string value of 65 is %s\n", chr(65))
