Specifies a default data type for a range of variable names

Syntax

` Defdbl start_letter[-end_letter ][, ...]

`

Parameters

start_letter

end_letter

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.

Examples

This will make aNum a Double-precision decimal number since it is in the range of a-d:

start GeSHi

'' 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.

end GeSHi

Dialect Differences

• Only available in the -lang qb and -lang fblite dialects.

Differences from QB
