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
