How to turn a relative path into an absolute path?
Dennis Halver
on various computers.
One of the first instructions is:
set basedir=%~dp0\..\..
How can I turn/convert this relative path into an absolute path (with no ".." back parent references)?

I believe this is an absolute path!
Despite the use of two 'back-tracking directories' - the path does begin
with a drive letter.
An absolute path (as far as I am aware) is one that can be worked out
from the information given, whereas :
.\system\ikons\
...would NOT be an absolute path, but :
c:\windows\system32\shellext\..\
..would be (simply being the equivalent of C:\windows\system32)
(I could be wrong about this but did think that an absolute path was one
that could be resolved from any location...)

Sure %~dp0 returns an absolute path but, AIUI, what the OP really wants to
get is the basedir (which is the first folder after the drive letter). In
your example that would be "c:\windows".

Please do not multi-post. The appropriate method is cross-post.

out, but I say there is no way to do this.
If you have some program that has specified that the base dir must be
%~dp0\..\.. this will turn out to be two dirs above that the batch
file is in (specified by parameter 0) - wherever it is.
If the batch file were in C:\WINDOWS\system32\macromed\flash to a batch
file containing %~dp0\..\.. then the result would be base dir =
C:\windows\system32 .... two dirs above
C:\windows\system32\macromed\flash....

Many OP's seem to explain what they want using poor pseudo examples or
incorrect nomenclature causing multiple interpretations as to what they
really meant/wanted.
However...
Since %~dp0 returns a trailing backslash, if current folder was
C:\WINDOWS\system32\macromed\flash
then %~dp0\..\.. would then return
C:\WINDOWS\system32\macromed\flash\batname.cmd\\..\..
(Note the double backslash)
Following even your logic, it is still unclear if OP wanted basedir to
return
C:\WINDOWS\system32\macromed\flash
or C:\WINDOWS\system32\macromed
because real examples were not provided.
We will have to wait for OP to post back to clarify which was actually meant
(basedir=x folders up, or basedir=rootfolder). Meanwhile, the previous code
I posted demonstrates walking up the path to the root folder regardless of
depth. Stepping back a fixed number of folders is even easier (what you
claim "there is no way to do this").
@echo off
for %%i in ("%~dp0..\..") do (set basedir=%%~dpi)
echo basedir=%basedir%

The program that wrote the batch, specified :
set BASEDIR=%~dp0\..\..
How would you specify it any different?
i.e. to resolve it to an "absolute path" as the OP requested, for a
batch file run from *any* directory?
And quit the "...even your logic" jibes - they are beneath you.

Honestly! The OP has not chimed in to clarify but you are still trying to
debate the OPs request based on the code. Did a program write it or did the
OP? OP never stated a program wrote it. Put this simple command in a batch
and see for yourself if it returns a valid path. Then move the batch to
other folders and try it. No folder you put it in will return a valid path.
@echo BASEDIR=%~dp0\..\..
While we are waiting for the OP to chime in, it would be particularly
appropriate for you to take the time to read up on proper quoting practices.
