Module Name:
MOFLEX.H
Abstract:
Declarations for class CMofLexer, which tokenizes MOF files. ANSI, DBCS and UNICODE are supported.
History:
a-raymcc 11-Oct-95 Created. a-raymcc 27-Jan-96 Update for aliasing. a-davj 6-June-96 Added support for octal, hex and binary constants and line stitching, comment concatenation, escape characters and old style comments.
