Line continuations and && in DOS

Notes to myself:

• && works in DOS too (only do step 2 if step 1 succeeded)


• Use ^ for line continuation


• Use %ERRORLEVEL%, labels, and goto, for some primitive flow control.

Here's an example


@echo off

set basedir=Z:\path\to\dir


cd %basedir% && ^
hg fetch -R .\MRA && ^
hg fetch -R ".\Super common" && ^
hg fetch -R .\ServerKpf

goto answer%ERRORLEVEL%
:answer0
echo hg fetch complete
komodo "%basedir%\ServerKpf\dev_util_nds_dev.kpf"
goto end
:answer1
echo Program had return code 1
pause
goto end
:end
