ORDCHR(3am) GNU Awk Extension Modules 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))
