DefLng
Specifies a default data type for a range of variable names
Syntax
`
DefLng start_letter[-end_letter ][, ...]
`
Parameters
`start_letter`
the first letter in the range
`end_letter`
the last letter in the range
Description
`DefLng` specifies that variables and arrays which aren't declared with a data type - or not declared at all - are implicitly declared of type `Long` if the first letter of their names matches a certain letter or lies within an inclusive range of letters.
Example
This will make `lNumber` a `Long` integer number since it starts with `l`.
`
'' Compile with -lang fblite or qb
#lang "fblite"
DefLng l
Dim lNumber ' implicit: As Long
Print Len(lNumber) ' Displays 4, the number of bytes in a long.
