windows - cmd script, How to pass token variable(say %%a) to a call -
this first question please bare.
serverlist= abc,def,xyz,.... each of these items comma seperated list b=apple,ball,cat...
i have batch script has nested loop following
setlocal enabledelayedexpansion %%a in ("%serverlist:,=" "%") ( /f "delims= " %%b in ( xxxxxxx) ( echo %%~a echo b %%~b call :header %%a %%b echo -------- ) ) :header ( echo inside header values %1 %2 ) output:
--------------------------------------------- abc b apple,ball,cat inside header values "abc" apple -------- def b apple,ball,cat inside header values "def " apple -------- i need complete list of b in :header process further. of getting first element of b in call.
putting formal answer comments:
if arguments batch subroutine have spaces or commas, should quote arguments when call subroutine:
call :header "%%a" "%%b".(thanks aschipfl) within subroutine, unquote arguments processing, use
%~1,%~2. can find out more variable manipulation @ ss64's syntax section, pages on variables, delayed expansion, , substrings.(thanks lotpings) protect subroutines; before entry point, put unconditional
gotoprevent execution "falling into" routine.
