DefDbl

FreeBASIC

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.
