Why is this section of my batch script not being executed? -

i'm having problem calling specific section of batch script. goal run script , have install given executables , run commands:

@echo off  echo 1. 32-bit echo 2. 64-bit set /p install="please choose correct installation: " set /p proxy="enter proxy gateway path if applicable environment: " 2>nul call :case_%install% if errorlevel 1 call :error rem case_%install% or error returns here echo done. pause exit \b  :case_1     rem install nodejs 32-bit     call node-v4.4.7-x86.msi     rem install ruby     call rubyinstaller-2.3.1.exe     goto next_task :case_2     rem install nodejs 64-bit     call node-v4.4.7-x64.msi     rem install ruby     call rubyinstaller-2.3.1-x64.exe     goto next_task :next_task     rem install sass css precompiler (v3.4.19)     call gem install sass --http-proxy %proxy%     rem install compass css plug-in (v1.0.3)     call gem install compass --http-proxy %proxy%     rem run node package install     cd ..     if not "%proxy%"=="" (         call npm config set proxy %proxy%         call npm config set https-proxy %proxy%     )     call npm install     rem instal grunt globally     call npm install -g grunt     rem install jshint globally because of warning     call npm install -g jshint     goto end_case :error     echo unable complete installation of tools     goto end_case :end_case     ver > nul     goto:eof 

this execute either case_1 or case_2 perfectly, depending on user chooses. nodejs installed, , ruby. then, when reaches end of 1 of sections, output:

done. press key continue . . . 

the script never follows goto run next_task, , never installs sass or compass , doesn't run npm commands.

i have noticed running script twice , skipping nodejs installation on second run executes next_task section correctly... - leads me believe there's sort of timing issue going on here.

other things have tried:

• replacing gotos calls (does not behave correctly)
• replacing section names referenced goto use format :{section} (no change)
• replacing calls before node , ruby executable start /wait (doesn't seem makes difference)

so, i'm stumped. appreciated.

i ended solving problem (using workaround) breaking script 2 separate scripts. unfortunately, i'm unable call 1 script other , gem , npm commands set (even through use of start create new environment, surprising me), solution. @aschipfl pointing out unnecessary use of call when referencing executables.

install_tools.bat (run first)
