Question about array
Posted: Sun Apr 12, 2009 12:55 AM

Hello,

How can I detect when a variable contains a single data or an array ?
In case it contains an array, how can I determine the dimension of this array ?

Thanks a lot for any help.

Code (fw): Select all Collapse

if ValType( uVar ) == 'A'
   // array
   nRows  := Len( uVar )
   if nRows > 0
      if ValType( uVar[ 1 ] ) == 'A'
         // 2 dimentional array
         nCols  := Len( uVar[ 1 ] )
      endif
   endif
else
   // not an array
endif
