3. Application Packer

A typical VICAR application program, procedure, or SUBLIB subroutine is composed of several files. These include source code, include files, PDFs, imakefiles, test files, documentation files, and others. In order to better manage all these files, they are packed into one file so they can be treated as a unit. These files are called COM files due to their ".com" extension. COM files are created and used via a pair of programs called vpack and vunpack (the "V" is for "VICAR").

vpack and vunpack are complementary, cross-platform programs which are designed to pack and unpack application COM files. A COM file typically includes source code, an imakefile, and a PDF file. The COM file may also include test files and other, application-specific files. Use vunpack to extract files from the COM file.
