Syntax
IsLower( <CharacterValue> )
Purpose
To determine if leftmost character in a character value is a lower case letter. It is the inverse of the IsUpper() function which determines whether a character begins with an uppercase character.
Both IsLower() and IsUpper() relate to the Lower() and Upper() functions which actually convert lowercase characters to uppercase, and vice versa.
Parameters
<CharacterValue> is the value to examine.
Returns
IsLower() returns a true/false (logical) value.
Usage
Because IsLower() returns a logical value, it is best suited for use with selections, not reports.
Example
The following examples illustrate IsLower():
CALL |
RESULT |
---|---|
IsLower("aBcDe") |
True |
IsLower("AbcDe") |
False |
IsLower("1abcd") |
False |
IsLower("abcd") |
True |
