[Massimiliano Gubinelli <address@hidden>]

Dear Marc,
 the manual contains many useful information about basic usage of TeXmacs, 
for example the section “Writing TeXmacs style files” contains info on 
writing macros. In your case you would simply type (inside TeXmacs)
\assign
eqref
\macro
lab | Equation \reference \lab

namely, the argument of the macro is retrieved as the variable \lab

Note that “edit preamble” put TeXmacs in a mode where you see commands as if 
they were “deactivated”, namely in source mode. In your case since you were 
already typing a macro in normal mode, it was surrounded by an \inactive tag 
(which allow macros to show up also in normal mode, for editing purposes), 
that is the reason of the additional tags when you swithc mode. TeXmacs do 
not have any way to understand your purpose so the behaviour is completely 
correct. Once you write a macro and activate it you will see it in “preamble 
mode” without the surroundings \inactive tags.

Best
Max
