program information file การใช้

• TopView first introduced Program Information Files ( PIF files ), which defined how a given DOS program should be run in a multi-tasking environment, notably to avoid giving it unnecessary resources which could remain available to other programs.
• The concept of Program Information Files was also used under Digital Research operating systems such as Concurrent DOS, Multiuser DOS, System Manager and REAL / 32, however, using the PIFED command, the necessary program information got directly embedded into the . EXE or . COM executable file.
