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 
	KeyPgDouble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 KeyPgDouble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 CompilerOptlang-lang qb and CompilerOptlang-lang fblite dialects.

Differences from QB
	* None
