Is there a way to pass parameters “by name” (and not by order) to a batch .bat file?

Question

I need to be able to pass parameters to a windows batch file BY NAME (and NOT by order). My purpose here is to give end user the flexibility to pass parameters in any order, and

Yeah you could do something like that though I don't think you can use "=" as a token delimiter. You could use say a colon ":", somebatchfile.bat "SOURC:originalFile.txt" "TARGET:newFile.txt". Here is an example of how you might split the tokens:

@echo off

set foo=%1
echo input: %foo%

for /f "tokens=1,2 delims=:" %%a in ("%foo%") do set name=%%a & set val=%%b

echo name:  %name%
echo value: %val%

Running this would produce this:

C:\>test.bat SOURC:originalFile.txt
input: SOURC:originalFile.txt
name:  SOURC
value: originalFile.txt

[Edit]

Ok, maybe it was too close to bed time for me last night but looking again this morning, you can do this:

@echo off

set %1
set %2

echo source: %SOURCE%
echo target: %TARGET%

Which would produce this (note that I reversed the source and target on the command line to show they are set and retrieved correctly):

C:\>test.bat "TARGET=newFile.txt" "SOURCE=originalFile.txt"
source: originalFile.txt
target: newFile.txt

Note that %1 and %2 are evaluated before the set so these do get set as environment variables. They must however be quoted on the command line.
