I'm working on a complex script; it employs nothing more than native commands for NT 5.2 and newer for compatibility purposes. I have a function within it that seems to be misbehaving and freezing up. Ideally it would be called "call :csvEdit "query:searchString" | "append:appendString"

The append section functions perfectly.

The query Does not. It is supposed to search each line of the file and list any line with a number to choose one that matches the query. The search string would then be parsed by a different function within the script to load the information into environmental variables. The output is environmental %csvOut%.

:csvDB :: "query:searchString" OR "append:appendString" (query will return the whole line or 0 for no match | appendstring will return 1/0 success/fail)

    if not x%str2:query=% == x%str2% goto :query
    if not x%str2:append=% == x%str2% goto :append
    if 1 == 1 (
        set output=error
        goto :333
        )
    :append
        for /f "usebackq tokens=2 delims=:" %%a in ('%str2%') do (
            echo %%a >> %netRoot%\customers.csv
            if %errorlevel% == 0 set output=1
            if %errorlevel% NEQ 0 set output=0
            )
    goto :333
    :query
        set /a "n=0"
        for /f "usebackq tokens=2 delims=:" %%A in ('%str2%') do (
