DefDbl

Specifies a default data type for a range of variable names

Syntax
   DefDbl start_letter[-end_letter ][, ...]

Parameters
   start_letter
      the first letter in the range
   end_letter
      the last letter in the range

Description
   DefDbl specifies that variables and arrays which aren't declared with a 
   data type - or not declared at all - are implicitly declared of type 
   Double if the first letter of their names matches a certain letter or 
   lies within an inclusive range of letters.

Example
   This will make aNum a Double-precision decimal number since it is in the 
   range of a-d:
   '' Compile with -lang fblite or qb

   #lang "fblite"

   DefDbl a-d
   Dim aNum 'implicit: As Double

   Print Len(aNum) ' Prints 8, the number of bytes in a double.

Dialect Differences
   * Only available in the -lang qb and -lang fblite dialects.

Differences from QB
   * None
