#pragma options [no]digraph
Enables recognition of digraph key combinations or keywords to represent characters not found on some keyboards.
A digraph is a keyword or combination of keys that lets you produce a character that is not available on all keyboards. For details on digraphs, see Digraph characters .
__DIGRAPHS__ is predefined to 1 when -qdigraph is in effect; otherwise it is not defined.
To disable digraph character sequences when compiling your program, enter:
xlc myprogram.c -qnodigraph
