# One space on each side of every binary operator (CodeCop AA0001)
|
|
|
|
## Description
|
|
|
|
CodeCop AA0001 requires exactly one space on each side of every binary operator: assignment (`:=`), arithmetic (`+`, `-`, `*`, `/`, `mod`, `div`), comparison (`=`, `<>`, `<`, `<=`, `>`, `>=`), logical (`and`, `or`, `xor`), and string concatenation. `x:=1+2`, `Price:=Amount*Quantity`, `if a=b then`, and `if a and b then` all violate the rule. The rule applies to the binary use of `-` (subtraction); the unary minus (`-Profit`) takes no leading space.
|
|
|
|
## Best Practice
|
|
|
|
Write `x := 1 + 2`, `Price := Amount * Quantity`, `if a = b then`, `if a and b then`. The standard AL formatter inserts these spaces automatically; running `Alt+Shift+F` (Format Document) in the AL extension is the simplest way to bring an entire file into compliance.

|
See sample: [`single-space-around-binary-operators.good.al`](single-space-around-binary-operators.good.al).
|
|
|
|
## Anti Pattern
|
|
|
|
`x:=1+2;`, `Price:=Amount*Quantity;`, `if a=b then`, `if a and b then`. All trip AA0001.
