The variable it uses is $INSTDIR, and you can modify $INSTDIR in function or section.

It's a variable, so you can change it like any other variable. StrCpy, ReadRegStr, ReadINIStr, ...

Section MainFiles

StrCpy $INSTDIR "$PROGRAMFILES\Foo\Bar"

SetOutPath "$INSTDIR"
...

SectionEnd

Errr... You're writing an installer in NSIS, and you're asking what language it is? It's NSIS script, duh.

Please read the documentation for information on what commands exist and what they do:
