VDEF is not very flexible; it reduces a timeseries to a scalar.  CDEF works
on timeseries to give a timeseries.  So the above creates a new timeseries
‘zusammen’ using a CDEF then uses a VDEF to convert it to a scalar (IE,
the ‘LAST’ operation)

how is it possible to add two LAST results and show in GPRINT?

I try with:
VDEF:last_1=maxaus_1,LAST \
VDEF:last_2=maxaus_2,LAST \
VDEF:last_zusammen=maxaus_1,maxaus_2,+ \

last_1 show  "25.03"

last_2 show "3"

last_zusammen show "25,21"

Thanks for an answer
