- { The grep text search programs consist of 3 binary files:
-
- REGEXP.DLL - Text search engine dynamic link library (DLL)
- that is written in Borland C++ 3.1 and
- shared by both TVGREP.EXE and OWLGREP.EXE
- OWLGREP.EXE - Windows grep program (uses ObjectWindows)
- TVGREP.EXE - DOS text mode grep program (uses Turbo Vision)
-
- REGEXP.DLL is a Windows format DLL and comes already built. To rebuild
- it, make sure Borland C++ 3.1 is on your DOS path, change to the
- \BP\EXAMPLES\GREP\DLL directory and then run MAKE.
-
- OWLGREP is a Windows application. To build it, set Compile|Target to
- Windows from inside the IDE or type the following command-line at a
- DOS prompt:
-
- bpc /m /cw owlgrep
-
- TVGREP is a DOS protected mode application (DPMI). To build
- it, set Compile|Target to Protected from inside the IDE or type the
- following command-line at a DOS prompt:
-
- bpc /m /cp tvgrep
