LCase and LowerCase (str) are equivalent functions. However, LCase is preferred in Basic syntax, whereas LowerCase is preferred in Crystal syntax.
LCase converts the given string to all lower case and returns it.
A good use of this function is when a field contains both uppercase and lowercase letters and you want to convert all letters to lowercase for consistency.
The following examples are applicable to both Basic and Crystal syntax:
Returns "ronald", where {customer.FIRST NAME} is "Ronald".
LCase ("BrEaD " + "AND " + "bUtTeR")
