  • Conv. Memory used by PB3.5 IDE

    Why would PB's IDE use different amounts of
    conventional memory on two different computers?
    Below is a comparison of the Dos MEM command
    before and after loading PB5.3.

    Computer ONE Pentium, Windows 98
    At Dos prompt, nothing loaded, C:>Mem
    Memory Type Total Used Free
    ---------------- -------- -------- --------
    Conventional 640K 72K 568K
    Load PB, Dos Shell, C:>Mem
    Memory Type Total Used Free
    ---------------- -------- -------- --------
    Conventional 640K 510K 130K
    Size of IDE: 438K

    Computer TWO Pentium III, Windows 98SE
    At Dos prompt, nothing loaded, C:>Mem
    Memory Type Total Used Free
    ---------------- -------- -------- --------
    Conventional 632K 36K 596K
    Load PB, Dos Shell, C:>Mem
    Memory Type Total Used Free
    ---------------- -------- -------- --------
    Conventional 632K 523K 109K
    Size of IDE: 487K

    Computer Two: 487K
    Computer One: 438K

    IDE Difference: 49K

    Net Difference in free space: 21K

    Oh yeah, computer One's Pb.exe, Pbc.exe, Pbconfig.pb, etc.
    were transferred directly to computer Two via diskette.
    There was not a new install on Two.

    Why would second computer PB ide use 49kb of memory than the first?

    Losing the net 21k for debug hurts!

    This looks like a difference in the way win98 and win98se run a
    dos box. On my laptop I get 438kb for PB in a dos box. If I run
    PB with a short cut I get 431kb for PB. This I think is because
    I am not starting a dos box and then envoking the compiler.

      I think Keith is on to something there, if you run a dos program
      from windows, it won't start a copy of command.com for that
      session. in fact, if you don't include a shell= line in your
      config.sys, you can actually run dos progs without any copy of
      command.com in running(as of windows 95 M$ included the code for
      command.com in with win.com). So an extra copy of command.com
      could be using some of that memory. also the first machine might
      have "LocalLoadHigh=On" set in the system.ini file, causing
      command.com to load high. also, differences in the environment
      settings can cause differences in memory useage in a dos box.

      But none of this seems to account for an entire 41k of mem, I
      would be interested in finding out more about this myself.
      Please update this post if you find out more.
