## Description
|
|
|
|
Variables that refer to a AL object must contain the objects name, abbreviated where necessary.
|
|
|
|
A variable must begin with a capital letter.
|
|
|
|
Blanks, periods, and other characters (such as parentheses) that would make quotation marks around a variable necessary must be omitted.
|
|
|
|
If a variable is a compound of two or more words or abbreviations, each word or abbreviation should begin with a capital letter.
