TRIGRAPH.EXE

Go Up to Command-Line Utilities Index

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 C++Builder 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.
