I must recall that thread again to notify that command is not working
from sindei a batch file :

:loop
set source=3D%dir%\%codeloop%
if /I %codeloop% GTR %MAX% goto :End

echo %source%
pause ""
pushd %source%
dir /b "%source%\TMP*.RPT"  > %source%\dir.txt
@for /F "tokens=3D*" %%* in (%source%\dir.txt) do (
@%binaries%\gawk -f %scripts%\alexbank_distribute_branches.awk %source%
\%%*  2> %scripts%\alexbank_distribute_branches.fil
echo from inside batch %codeinsidebat%
pause ""
)


My alexbank_distribute_branches.awk does not produce the value to
codeinsidebat variable using that statement :

ENVIRON["codeinsidebat"]=3Dcodeawk
