> could you please enlighten the rest of the universe in what way you > determined that 'The Watcom build runs faster' ok, I enlightened myself, downloaded https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/unofficial/metados/metados-0.6.zip unpacked it, and made METADOS.IMG the start diskette of a virtual box. and this behaves indeed strange and complicated. METADOS is an example of batch processing, unzipping stuff to RAM disk, unzipping further, and rather difficult to debug indeed :<< first experiments, replacing the original command.com with command 84 pre5 prerelease, with command-turbo.exe: execution needs 1:05 minutes (as seen by CPU time used in windows task manager) from start to finish. there's a MEM.BAT which will fetch MEM.EXE from somewhere, then execute it. seems to fetch indeed and work. with command-watcom.exe, execution needs only 16 seconds. however the directory G:\UTILS\ is never filled, MEM.BAT does not exist, and MEM --> missing command with command-gcc.exe, sometimes (~50%) execution ends in an endless loop, and crashes even the virtual box, and must be killed using the task manager. when it finishes (~50%), execution needs only 34 seconds. and the directory G:\UTILS\ is filled, MEM.BAT does, MEM.EXE is fetched and executed - and crashes the system. indeed strange things are happening. just to notify everybody else that I will try to narrow down this better Tom >> but my TESTS.BAT > ' my TESTS.BAT' ? are we assumed to know what that is? > the world famous TESTS.BAT? >> just silently fails. > eventually comment out 'echo off', and tell us what specifically fails >> And the others (Turbo and GCC) seem to later on >> cause "Invalid Opcode". > I have seen a lot in the last many years, but never 'seem to cause > "Invalid Opcode"'. > Either it does, or it does not.
