Already answered, but not correctly. You could e.g. use the first word
of the first value. This works:

. l

     +------------------------------+
     | var1   var2             var3 |
     |------------------------------|
  1. | Frog   Toad   Venomous snake |
  2. |    1      2                3 |
     +------------------------------+

. renvars , map(`=word("@", 1)')

. l

     +------------------------------+
     | Frog   Toad         Venomous |
     |------------------------------|
  1. | Frog   Toad   Venomous snake |
  2. |    1      2                3 |
     +------------------------------+
