Solve : Way to Tell if Parameters exist or not??

1.	Solve : Way to Tell if Parameters exist or not??
Answer» Hello All, I'm trying to create a batch FILE that accepts a parameter but if the parameter does not exist I want to echo to the user that they need to provide the parameter.. Otherwise I want to use the parameter. Is there a WAY to know if the user has entered a parameter. I've tried %1==NUL, %1=="" and NOT EXIST %1 all to no eval... I'm pretty SURE you can do this, but OBVIOUSLY I just don't know how. Any assistance greatly APPRECIATED. ThanksIf you use the form: IF X%1 == X GOTO NOPARM ... it will take the branch if there is no parameter present. Thanks a bunch..
