gawk: Extension Sample Ord

1 
1 16.7.5 Character and Numeric values: 'ord()' and 'chr()'
1 --------------------------------------------------------
1 
1 The 'ordchr' extension adds two functions, named 'ord()' and 'chr()', as
1 follows:
1 
1 '@load "ordchr"'
1      This is how you load the extension.
1 
1 'number = ord(string)'
1      Return the numeric value of the first character in 'string'.
1 
1 'char = chr(number)'
1      Return a string whose first character is that represented by
1      'number'.
1 
1    These functions are inspired by the Pascal language functions of the
1 same name.  Here is an example:
1 
1      @load "ordchr"
1      ...
1      printf("The numeric value of 'A' is %d\n", ord("A"))
1      printf("The string value of 65 is %s\n", chr(65))
