One of the first lines in a batch file I have is this:
IF '%FirstServer2%' == 'No' goto :SkipSolution The variable %FirstServer2% is not declared anywhere, so it must be passed to the batch file somehow. So, how can I pass in the value?
Simply set the environment variable beforehand and start your batch afterwards.
Named parameters are a bit misleading in this case, as
FirstServer2is just a normal environment variable.I have used a similar technique in a batch I wrote once which was pretty configurable. Depending on whether variables were set or not it assumed some default values or went with already defined ones. This is a pretty useful technique if you want to avoid excessive parsing of parameters passed directly to the batch.
