[Limdep Nlogit List] Problem with NLCONVERT

[William Greene]

Alessandro: I assume you are using NLOGIT 6.  Superficially, the command
looks correct.  I suggest
you try the following:  Use the command

CLIST ; Convert = choice1,prezzo, vite1, vite_sa1,
             AGRITUR1, BIO1, COMPUTR1, SIT_WEB1,ETA1, SEX1, ANNSTUD1,
              AGR_STU1, PT_MAGG1, PT_MIN1, STRANER1, LAV_INT1, NMEMBR1,
              N0_5_1, N6_13_1 $

to create a labeled list that contains the 19 names.
Then, change the ;Names=... part of your command to

;Names = Convert $
