Zlatin,

Ok based on running this code:

select expanded, 00 + iif( occurs( '...',tip )>0, 27, occurs(',', tip) + iif(empty(tip),0,1)) as args ;
  from foxcode ;
   into cursor funcargs ;
   where type = 'F'

select args, count(*) from funcargs into cursor x1 group by 1 order by 1

We get this distribution of number of arguments to the builtin functions:

# Args       Cnt       	
     0         3
     1       193
     2       111
     3        69
     4        20
     5         8
     6         4
     7         1
     8         1
    27        11

The 27 arguments occur because of functions like min(), max(), createobject()
