    repeat
        ...
    until next() = 0;
end;

if FindSet() then
    repeat
        ...
    until next() = 0;

Example 2

Bad code

if IsAssemblyOutputLine then begin
    TestField("Order Line No.", 0);
end;

Good code

if IsAssemblyOutputLine then
    TestField("Order Line No.", 0);

// Except for this case
if X then begin
    if Y then 
        //DO SOMETHING;
end else 
    (not X)

Tips

The AZ AL Dev Tools/AL Code Outline extension adds two new commands to Visual Studio Code to remove begin..end around single statements.

• Remove Begin..End around Single Statements from the Active Editor : removes begin..end around single statement from the current editor
• Remove Begin..End around Single Statements from the Active Project : removes begin..end around single statement from the current project
