## 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.

## Example 1

### Bad code

```al
    WIPBuffer: Record "Job WIP Buffer"
```

### Good code

```al
    JobWIPBuffer: Record "Job WIP Buffer"    
```

## Example 2

### Bad code

```al
    Postline: Codeunit "Gen. Jnl.-Post Line";    
```

### Good code

```al
    GenJnlPostLine: Codeunit "Gen. Jnl.-Post Line";
```

## Example 3

### Bad code

```al
    "Amount (LCY)": Decimal;    
```

### Good code

```al
    AmountLCY: Decimal;        
```
