Reading Console Output
After much hunting around I havent found the answer to this question, so its time to turn to you guys.

I need to execute a console command and read the output into an NSIS variable so I can then use it elsewhere.

As an example the following command:

adsutil.vbs ENUM /P W3SVC

outputs

[/W3SVC/Info]
[/W3SVC/Filters]
[/W3SVC/1]
[/W3SVC/2]
[/W3SVC/3]
[/W3SVC/4]

I need to get the last [/W3SVC/X] entry, increment the X number by one and put the result into an NSIS variable so that I can then use it elsewhere, e.g.

nsExec::ExecToLog /TIMEOUT=5000 'cscript.exe //B c:\inetpub\adminscripts\adsutil.vbs START_SERVER W3SVC/$R0'

Use nsExec::ExecToStack.

Thanks for that, wood for the trees situation I thinks.

For the benefit of anybody searching these forums in the future I was looking for a way to get NSIS to create and configure a new IIS site. The following is the relevant NSIS code

;get the last W3SVC id
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs ENUM /P W3SVC'
        Pop $0 ;return code
        Pop $1 ;output
        
        ;parse out the last W3SVC id from $1 output
        StrCpy $2 $1 "" -6
        StrCpy $3 $2 1
        
        ;increment result by 1
        IntOp $4 $3 + 1
                
        ;create new site (using incremented last number in /W3SVC/X from output above)
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs create_vserv W3SVC/$4'
        
        ;copy settings from root site
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs copy W3SVC/$3 W3SVC/$4'
        
        ;name the new site
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs set W3SVC/$4/ServerComment "SiteNameGoesHere"'
        
        ;set new site to listen on 443 for SSL
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs SET W3SVC/$4/SecureBindings ":443:"'
        
        ;set new home directory
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs SET W3SVC/5/Root/Path "C:\RootDirectory"'
        
        ;Start new site
        nsExec::ExecToStack 'cscript.exe c:\inetpub\adminscripts\adsutil.vbs START_SERVER W3SVC/$4'
