16.7.5 Character and Numeric values: ord() and chr()

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

@load "ordchr"
This is how you load the extension.


number = ord(string)
Return the numeric value of the first character in string.


char = chr(number)
Return a string whose first character is that represented by number.

These functions are inspired by the Pascal language functions of the same name. Here is an 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))
