Hello, all:
I was paging through some Sourcer listings that I have of the
Windows 1.04 code and noticed that most of the functions in the DOS Shell
code (MSDOS.exe and MSDOSD.exe) are referenced by ordinal number and not
function name ("MSDOS_23" versus "DoSomeThing"). So, I was wondering
if
anyone had a copy or knows the existence of SDK documentation for Windows 1.

most of the functions in the DOS Shell code (MSDOS.exe
and MSDOSD.exe) are referenced by ordinal number
Early (most?) DOS techinical reference
manuals listed function calls by numbers,
E.G. 10H = Close file. 01H = Keyboard input, etc.
Could this be it?

Two different concepts. The DOS tech refs are refering to the values to place in ah (I
think, or was it al?) before making a DOS or BIOS int call. This is all pre-DLL days.
Richard is referring to
the ordinal number within a DLL to reference a specific function located in the DLL. Not
all functions in a dll have their names exported and sometimes the only way to get to them
is by ordinal
number. This is one way that M$ creates 'value added' to their software by
utilizing these undocumented calls.

"Sourcer listings" are disassemblies.
You don't want, or need Win SDK for THIS (plenty of use for it for other
stuff!)
What you need is a copy of the DOS Technical Reference, or ANY of the
after-market programmer's references, that will provide you a list of the
MS-DOS (aka INT 21h) functions, so that you can substitute
"DoSomething" in lieu of function "23".
Note: the DOS Technical Reference consists of what used to be the
appendices of the DOS manual in version 2.00 and below. In version 2.10,
they did an appendectomy.
BTW, Norton refers to the functions by DECIMAL numbers, whereas the entire
civilized world always refers to them in hexadecimal. For example,
function 30h of INT 21h reports DOS version, (as opposed to function 48 of
int 33 in Norton-speak)
