TRIGRAPH

Trigraphs are three-character sequences that replace certain characters used in the C language that are not available on some keyboards. Translating trigraphs in the compiler would slow compilation down considerably, so CodeGear C++ provides a filter named TRIGRAPH.EXE to handle trigraph sequences.

Command Line Syntax

trigraph [-u] <filename> [...]

TRIGRAPH Options

TRIGRAPH has three command options:

-nXXX writes output files to the directory named in XXX.
-u means to Undo insert trigraphs.
-xXXX creates output files with the extension XXX.

The following table shows the trigraph sequences the TRIGRAPH recognizes:
