I found this batch file password generator:

rem 16 stings pwd

setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
set alfanum=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789

set pwd=
FOR /L %%b IN (0, 1, 16) DO (
SET /A rnd_num=!RANDOM! * 62 / 32768 + 1
for /F %%c in ('echo %%alfanum:~!rnd_num!^,1%%') do set pwd=!pwd!%%c
)

echo pwd=%pwd%

which I put into a batch file: rand.bat
However when I call rand.bat from another batch file, the environment variable pwd is no longer available. How do I get it to persist into the calling batch file?

windows batch-file

Exiting the called batch implies an Endlocal which discards all created local variables.

To overcome this include an Endlocal command and on the same line repeat the set command.

rem 16 stings pwd

setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
set alfanum=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789

set pwd=
FOR /L %%b IN (0, 1, 16) DO (
 SET /A rnd_num=!RANDOM! * 62 / 32768 + 1
 for /F %%c in ('echo %%alfanum:~!rnd_num!^,1%%') do set "pwd=!pwd!%%c"
)

echo pwd=%pwd%
Endlocal & set "pwd=%pwd%" & goto :Eof
