Your problem is not to access a heap variable, but rather to return
the value from OPEN_LANG. You can do that by turning it into a
function:

FUNCTION open_lang,path,fitxer_catalog
oMsgCat=MSG_CAT_OPEN('',FILENAME=path+fitxer_catalog)
return, oMsgCat
END

And then calling it:
mycat = open_lang('/lang/', 'msg.cat')

Good luck,
Craig
