Do not wrap a single statement in begin … end (CodeCop AA0013)
Description
CodeCop AA0013 flags begin … end blocks that contain exactly one statement. The compound-block syntax exists to group multiple statements as a unit; using it for a single statement adds two lines and a level of nesting without adding meaning. if IsAssemblyOutputLine then begin TestField("Order Line No.", 0); end; should be if IsAssemblyOutputLine then TestField("Order Line No.", 0); — one statement, no block. The same logic applies after else, for, while, and repeat.
Best Practice
A single statement following then, else, do, or a case label is written on its own line, indented one level, with no begin … end. Use begin … end only when there are two or more statements to group.

Anti Pattern
if Cond then begin OneCall(); end; — single statement wrapped in a block. AA0013 flags it. The reviewer signal is "a begin followed by exactly one statement before its end."
