Which 1.5 Details

Publisher Description

Which is a Java utility for Windows that searches the path and tells where it finds a given exe or dll. It further tells you what type of exe/dll it is, i.e. DOS 16-bit, Windows 16-bit, Windows 32-bit, Windows AMD 64-bit, Windows Itanium 64-bit, Jet 32-bit or Jet 32-bit that is out of date, and needs to be recompiled for the latest runtime. If you use the Jet version you use by typing: Which.exe someprog.exe or Which.exe somedll.dll on the command line. If you have *.jar set up as an executable extension you can type which.jar someprog.exe Otherwise you will have to type the verbose: java.exe -jar which.jar someprog.exe It sets the retcode depending on what it found: retcode Type 8 DOS 16-bit 16 Windows 16-bit 32 Windows 32-bit 33 Windows 32-bit Jet 34 Windows 32-bit Jet, out of date 64 Windows AMD 64-bit 65 Windows AMD 64-bit Jet 66 Windows AMD 64-bit Jet, out of date 70 Itanium 64-bit 90 an unknown type 91 unable to find/read the file 99 syntax error You may have other utilities called Which. Make sure you are using this one. WHAT IS JET? JET is an AOT Ahead Of Time Java Compiler that converts Java class files into ordinary *.exe files that look like conventional C/C++ executables to the end user. They load and execute faster than ordinary Java jar files. They require a DLL run time to work. WHICH tells you which of your executables are JET-complied which require the JET runtime and which do not. WHICH warns you when you have JET-compiled executables that would benefit from recompiling for the latest runtime. You can read more about JET at the website. Beware. You may also have a copy of JPSoft Which or Cygwin Which on your computer. You may think you are using CMP Which, but you could be using one of these. ICON Why the clothesline icon? The clothes represent the various directories hanging off the path.
