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))
