batch file - 'The Syntax of the command is incorrect'

Question

I've been making a text-adventure, but towards the end of my coding it came up with this error. Every time I try to continue from scene 5 to scene 5.1 it goes to a different scene and skips through it. Help?

Here is my code:

cls
echo You walk in through the doorframe, and into the dark room. You can't see a thing in the gloom, but when you put your hand on the wall you recognise the shape of a lightswitch.
echo.
pause
goto scene5.1

cls
echo You walk in through the doorframe, and into the dark room. You can't see a thing in the gloom, but when you put your hand on the wall you recognise the shape of a lightswitch.
echo.
pause
goto scene5.1

:scene5.1
cls
echo You flip the lightswitch down, and slowly the glowing bulbs switch on; illuminating the living room. In the gradually increasing light you see a table in the corner, and a large sofa that streches across the back wall. A few metres in front of the couch is a fireplace.
echo.
echo 1) Table
echo 2) Sofa
echo 3) Fireplace
echo 4) Go back
set /p type
if %type%==1 goto scene5.1.1
if %type%==2 goto scene5.1.2
if %type%==3 goto scene5.1.3
if %type%==4 goto scene5.1.4

Answer 1

@ECHO OFF
SETLOCAL

:scene4.6.1
:scene5.1
SET "scene=5.1"
cls
echo You flip the lightswitch down, and slowly the glowing bulbs switch on; illuminating the living room. In the gradually increasing light you see a table in the corner, and a large sofa that streches across the back wall. A few metres in front of the couch is a fireplace.
echo.
CALL :addchoice Table Sofa Fireplace "Go back"

GOTO makechoice

:scene5.1.1
ECHO AT table
goto :eof

:scene5.1.2
ECHO AT sofa
goto :eof

:scene5.1.3
ECHO AT fireplace
goto :eof

:scene5.1.4
:scene4.6
SET "scene=4.6"
echo You are IN a dank corridor dimly lit by sputtering torches
echo.
CALL :addchoice Doorway Corridor
GOTO makechoice


:makechoice
CHOICE /C %choices% 
SET "scene=%scene%.%errorlevel%"
SET /a choicecount=0
SET "choices="
GOTO scene%scene%

:addchoice
SET /a choicecount+=1
ECHO %choicecount%) %~1
SET "choices=%choices%%choicecount%"
SHIFT
IF "%~1" neq "" GOTO addchoice

GOTO :EOF

This may save you a heap of programming. Please do not accept it as an answer since bgalea's answer actually answers your question. This is just an approach to make the construct-an-adventure exercise faster and easier.

For each scene, describe the scene and call :addchoice with parameters of the available choices. If a choice is multiple words, "enclose them in quotes".

The routine assigns 1 to the first choice in the list, 2 to the next and so on. The available choices are then recorded in choices.

go to makechoice. This prompts for an entry using the list in choices. Then append dot+the errorlevel of the response to the current scene number, clear the choices and goto scene+the calculated scene number.

Note that you can use an empy command-sequence to move between scenes by using the structure like in scene5.1.4 to scene4.6 (iow, scene 5.1+choice4 moves to 4.6)

This way, your response-sets become one line after your scene description and you never need to use a series of if-commands to move between scenes.

Answer 2

C:\Windows\system32>echo 4) Go back
4) Go back

C:\Windows\system32>set /p type
The syntax of the command is incorrect.
goto was unexpected at this time.

It's probably the lack of an equals sign in set /p (well I know it is).

PS: Set /p var = PromptText is not the best command. It doesn't prevent wrong entry, and you don't check for it. Use Choice command instead. It only takes allowed entry.

The reason most examples use set /p is because choice was dropped from one windows version 15 years ago. That was along time ago.

CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]

Description:
    This tool allows users to select one item from a list
    of choices and returns the index of the selected choice.

Parameter List:
   /C    choices       Specifies the list of choices to be created.
                       Default list is "YN".

   /N                  Hides the list of choices in the prompt.
                       The message before the prompt is displayed
                       and the choices are still enabled.

   /CS                 Enables case-sensitive choices to be selected.
                       By default, the utility is case-insensitive.

   /T    timeout       The number of seconds to pause before a default
                       choice is made. Acceptable values are from 0 to
                       9999. If 0 is specified, there will be no pause
                       and the default choice is selected.

   /D    choice        Specifies the default choice after nnnn seconds.
                       Character must be in the set of choices specified
                       by /C option and must also specify nnnn with /T.

   /M    text          Specifies the message to be displayed before
                       the prompt. If not specified, the utility
                       displays only a prompt.

   /?                  Displays this help message.

   NOTE:
   The ERRORLEVEL environment variable is set to the index of the
   key that was selected from the set of choices. The first choice
   listed returns a value of 1, the second a value of 2, and so on.
   If the user presses a key that is not a valid choice, the tool
   sounds a warning beep. If tool detects an error condition,
   it returns an ERRORLEVEL value of 255. If the user presses
   CTRL+BREAK or CTRL+C, the tool returns an ERRORLEVEL value
   of 0. When you use ERRORLEVEL parameters in a batch program, list
   them in decreasing order.

Examples:
   CHOICE /?
   CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."
   CHOICE /T 10 /C ync /CS /D y
   CHOICE /C ab /M "Select a for option 1 and b for option 2."
   CHOICE /C ab /N /M "Select a for option 1 and b for option 2."

As help says use errorlevels in descending order

if errorlevel 4 dosomething
if errorlevel 3 dosomething
if errorlevel 2 dosomething
if errorlevel 1 dosomething
if errorlevel 0 UserPressedCtrl+C

or in any order

if errorlevel 1 if not errorlevel 2 dosomething for 1

Do not use %errorlevel% as it can be overwritten by other programs.
