I am trying to make a little connect four game and whenever I hit enter without typing anything into the console it says that goto was unexpected at this time All I want it to dos go back to :X for now if there is no user input. Any help would be aappreciated.
:X
cls
echo --------------
echo Connect Four X

回答1:
If you are entering a string with a set/p, then there's no saying that the data entered doesn't contain Spaces. The way to get over that is to "enclose the strings on both sides of the comparison operator in quotes" - that is, double-quotes 'not single quotes'
IF syntax is if string1 operator string2 action.
You need
if "%possiblyemptyvariable%"=="1" goto ...
