批处理 - “此时转到意外”

Question

Here is the batch script I am working on:

@echo off

:programBEGIN
set FILE=R3D-%input1%.txt
mode con:cols=24 lines=25
color F

set /p input1=}} INPUT: 
cls
if %input1%=="" goto ERR1
goto programLIST

:programLIST
echo Hello

:ERR1
echo Test
pause

Whenever I attempt to run the bat file and input no value, it closes with a quick prompt of "goto was unexpected at the time"

Is my formatting of the if statement correct, or is that the reason it keeps closing?

Answer 1

Because if input is not defined the script looks like this:

if =="" goto ERR1

Which is a syntax error.

Try like this:

if "%input1%"=="" goto ERR1

Answer 2

Instead of using that if statement, try this instead:

IF DEFINED input1 goto ERR1

If you must use the normal if statement, you can try this:

IF "%input1%"=="" goto ERR1

just to make sure. Other than that, I don't see where the problem would stem from.
