Casing

◼Correct case for types like: False, True, Boolean, Integer, Double, Cardinal, Byte, Pointer, LongBool, Single, Double, PByteArray, PWordArray, PByte, DWord, Variant, PChar, PWideChar, etc.
◼Ensure lower case for: string, nil, try, finally, except, begin, end, if, then, else, var, const, type, out, class, inherited, deprecated, experimental, inline, set, record, array etc.
◼TitleCase for parameters and method names
◼camelCase for local vars
◼Consts must include underscores and Title_Case is preferred
◼Defines are lowercase: {$ifdef}, {$else}, {$endif}, {$define}, {$undef}, {$include}. Except for {$ifNdef} which uses a capital N
◼Fields are TitleCase with a lowercase f. Global vars are prefixed with a lowercase g
◼VCL directives like {$R-} and {$Q-} are uppercase
◼Other preferred casing: FileName, Result, HResult

Spacing

◼No spaces before colons when a parameter or var block (ok in case statements, for example).
◼Always a space after a colon for vars, parameters, etc.
◼Binary operators: space around :=, =, +, <, >, <=, >=, <>, etc.
◼Spacing within brackets when a local comparison (everywhere except method parameters), e.g. "if ( x > 0 ) then..."
◼For any indentation, use double spaces

Line Breaks

◼There should always be a hard return after a raise exception or exit (unless followed by end or inside an except block)
◼No hard return after begin, except or finally. Generally no hard return before end (except for readability like with case statements)
◼begin and else must always be on the next line, not "if x then begin" or "end else"

Other

◼Methods without parameters (calls and declarations) should include empty brackets();
◼Float literals: 1.0, not 1
◼Value parameter for property settings is always named v, e.g. procedure TClass.SetXYZ(const v: string);
◼Local methods within a method should have _Underscore() prefix
◼Empty lines between local methods within a method should be {}
◼begin/end not required for single code lines
◼Preferred comment style: // or {}
◼Avoid any magic strings
◼Boolean variable/property naming: should start with Is, Has, Can
◼All units must include {$I ie.inc}
◼Avoid use of "with". Use explaining vars instead
◼AnsiString methods should have an A suffix, WideString should have W, string should NOT have S

Preferred Names for Local Vars
