Jam language question

OK, sorry for the "simple" question, but how the heck are you supposed to 
concatenate two strings?

I tried:

VC80_ROOT ?= "$(VS80COMNTOOLS)"..\\.. ;
VC_TOOL_PATH = "$(VC80_ROOT)"\\bin\\ ;
VC_SETUP = "CALL \"$(VC_TOOL_PATH)VCVARS32.BAT\" >nul" ;

But ended up with:

"C:\Program..\.. Files\Microsoft..\.. Visual..\.. Studio..\.. 
8\Common7\Tools\..\..\bin\VCVARS32.BAT" >nul

So then I tried:

local temp1 = "$(VS80COMNTOOLS:P)" ;
local temp2 = "$(temp1:P)" ;
VC80_ROOT ?= "$(temp2)" ;
VC_TOOL_PATH = "$(VC80_ROOT)"\\bin\\ ;
VC_SETUP = "CALL \"$(VC_TOOL_PATH)VCVARS32.BAT\" >nul" ;

but ended up with:

"C:\ 8\Common7\bin\VCVARS32.BAT" >nul

what's going on here?

Thanks!

John.
