Searching for Overlaydos.library

[Joe Maroni]

i already searched where i may find it, but it seems that it doesn´t exists anymore.

or does anyone of you still have it somewhere on disk..???

:confused

[bippym]

what's it do?

[Joe Maroni]

i don´t know...perhaps its switching of the DOS environment better than the standard library functions...:confused

or it allows disable interrupts, DMA access etc...

Did a quick Google search it seems like might be on "The One" coverdisk 1-0193b.adz:

Downloaded this and took a look using DirOpus but couldn't see the file :sad

What program needs this?

It sounds like one of those libraries that should be in the Kickstart ROM...

Seems like this is false alarm. All what I found were Titanics Cruncher packed files which use overlays (http://en.wikipedia.org/wiki/Overlay_(programming)) and the "Overlaydos.library" string disappears after decrunching the files. Also a reassembler break this up in a BCPL string containing 7,"Overlay" just before the "dos.library",0 string as the OpenLibrary call points only to the latter.

[Joe Maroni]

i need the library for "Moon Child", which was never released.

i only see in the header of the executable that there is such a library used...:rolleyes

[Codetapper]

As rgen says, there is no such library. The overlay text appears at the beginning of the file to indicate to dos that the file is overlaid.

[Joe Maroni]

this means, that the lib is not required..?

[Graham Humphrey]

Well surely if it doesn't exist then it can't possibly be required ;)

[Joe Maroni]

i´m sure that there is such a library..not just a string after decrunched files...

....................................`..l......................[..Overlaydos.library.....Moon Child demo by Team Hoi... please wait!.............

this is an ASCII shortcut from the Moonchild Demo...it looks like the lib is mentioned in the hunks of the exe to save enough space for it later....:confused

[Graham Humphrey]

So have you actually tried running it then?

[bippym]

disassemble it or up it to the zone ;)

[thor]

BCPL string isn't 0-terminated, so "Overlay" and "dos.library" seem to you to be one string but they aren't.

[Joe Maroni]

disassemble it or up it to the zone ;)

you´ll all get the file with an aGTW update..not earlier...:)

sorry, but we need to keep everything exciting...:D

but first i need to get it running...:p

[bippym]

Wel okay you'd better dis-assemble it then ;)

[rgen]

up it, I'm interested in this file anyway.

x_to, this is just a strange coincidence as two concepts hit each other here. A normal string has the text and a zero at the end to terminate it, a BCPL string has its size in the first byte and then the text, without any termination. So when this two strings meet, they look like one string, but they are two. Make a hex dump and you should see a 7 before the "Overlay" text starts. Have you tried the xfd package to see that this is a Titanics Cruncher file?
