Batch logical operators

[mbrink]

I'm trying to write a batch program to make a daily checklist of proceedures based on what day it is. But I can't find anything for operators like AND or OR to use in IF statements for Win2K command prompt. If need be, I could use nested IFs for AND, and separate IFs for OR, but some of the situations are so complicated that it would be a mess to write, and even worse to try to read afterwards if something needs to be changed.

Does such a feature exist for Win2K commend prompt? ANd if so, how?

Hello mbrink,

You have conditional processing symbols avail:
and ==> &&, &
or ==> ||

Check out the comand shell overview

How compound them is up to your imagination. For instance,
if dir filename.txt > nul && %fname%=="" set fname=filename.txt
will set the environment fname to filename.txt if filename.txt exists here (the 2nd command will not evaluate if the first successful for &&)
