JSI Tip 3686. Batch script returns physical and available memory, number of processors, and OS version information


Using GetSysInfo.exe, I have scripted GetMPO.BAT, which returns the following environment variables:

Environment   
Variable
 
 D e s c r i p t i o n 
 jsipm   A character-based variable containing the number of bytes of physical memory. 
 jsipmk   An arithmetic variable that contains the number of kilobytes of physical memory. 
 jsiam   A character-based variable containing the number of bytes of available memory. 
 jsiamk   An arithmetic variable that contains the number of kilobytes of available memory. 
 jsinp   An arithmetic variable that contains the number of processors. 
 jsios   A quoted text string that contains the OS version. 

GETMPO.BAT contains:
