command line:
In abc.bat, define a subroutine func1. In func1, get valOfI and valOfO from command line. Order of “-i valOfI” and “-o valOfO” can be any in command line.

Thanks

Very appreciate for your help and patience. Your explanation is valuable and rare. Very clear and helpful and into detail. Hope this could help others.

Thanks.

Sorry, I have not state my question in accuracy. This is another question. I want to know why following two commands have different output: echo " %str1% echo %str1% if definition of str1 is: set str1="a^!bcd^!efg^^^^^^^^^^^!^^^^^^^!^^^^^^^^^^!hi^^^^^^^^^!^^^^!^!" or if definition of str1 after remo...

I do not understand clearly from your explanation why code:
need phase 2, but code:
does not.

output of code: echo %str1%
thanks

Is it because third exclamation mark is escaped and lost its special meaning, so it and fourth exclamation mark cannot be used to expand variable?

Hi Dave,

Thank you for your help. The content is very detailed.

One question: after phase 2, why third ! and ^^ and fourth ! does not expand to value of variable ^^, but only stripe fourth ! .

thanks

look at this link: viewtopic.php?f=3&t=9137

I want to research how the example in link above works when I assign const string to variable str1

thanks

code: set "^=escapeOnly" set hi=hi001 set str1="a^!bcd^!efg^^^^^^^^^^^^^!^^^^^^^^^^^!^^^^^^^^^^!hi^^^^^^^^^!^^^^!^!" echo ----- original ---- echo !str1! echo ----- other 4 ----- 2x echo " %str1% output: ----- original ---- "a!bcd!efg^^^^^^!^^^^^!^^^^^^^escapeOnly " ----- other 4 ----- 2x " "aefg^!^...

In ‘other 2’ in your code, can I understand in this way:

1. remove all caret
2. collapse all consecutive opening exclamation mark into one
3. expand variable between two exclamation marks from left to right

code: :test1 setlocal EnableDelayedExpansion set "filename=temp1.txt" set "str1=" & <"%filename%" set /p "str1=" echo output 1 set str1 echo !str1! echo %str1% echo output 2 set "str2=%str1%" set str2 echo !str2! echo %str2% endlocal goto :eof content of temp1.txt abc %%var1%% ^!^!var2^!^! mmm !var3...

Hi Antonio,

Thanks for your help, your code works well.

:test2 setlocal DisableDelayedExpansion set "line1= abc # %%var1%% # ^!var2^!" for /f "usebackq delims=# tokens=1,2,3*" %%i in ('%line1%') do ( echo {%%i} echo {%%j} echo {%%k} ) endlocal goto :eof There are 3 space characters at both sides of “abc” in variable line1. But after I split line1 by for...

Hi Steffen,

In your code, if add “setlocal EnableDelayedExpansion” to beginning of function test6 and “endlocal” at end of test6, how could you make it work?

Thanks

Hi Steffen, Look following code: :test6 setlocal EnableDelayedExpansion set "lines_cnt=2" set "in_file=temp.txt" set "line=" set /a "n=0" <"!in_file!" ( for /l %%j in (1 1 !lines_cnt!) do ( set "line=" &set /p "line=" if defined _ret ( set "_ret=!_ret!^&" ) set "_ret=!_ret!set %~1[!n!]=!line! set /a...
