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, or -1 if there was a
    conversion error.

chr()

    This function takes a numeric argument and returns a string whose
    first character is that represented by the number. It returns the
    empty string if there was a conversion error.

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

NOTES

As of release 5.4 of gawk, these functions suport wide-character code
points.

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))
