	While the diamond operator (<big><big>{diamond}</big></big>) can be used in an immediate statement to the Session Manager, it is most commonly used in a [[functions\|function]] to start a new statement on the same line. It is used similarly to the semi colon ('''<big>;</big>''') in C, Pascal, PHP and many other languages, or the colon ('''<big>:</big>''') and backslash ('''<big>\</big>''') in some versions of Basic. It allows another statement to be ~~entered~~ on the same line.		While the diamond operator ('''<big><big>{diamond}</big></big>''') can be used in an immediate statement to the Session Manager, it is most commonly used in a [[functions\|function]] to start a new statement '''on the same''' physical line-row of user-code. It is used similarly to the semi colon ('''<big>;</big>''') in C, Pascal, PHP and many other languages, or the colon ('''<big>:</big>''') and backslash ('''<big>\</big>''') in some versions of Basic. It allows another statement to be concisely set on the same line.

	'''Note:''' The <big><big>{diamond}</big></big> operator cannot be used after a [[lamp]] (<big><big>{lamp}</big></big>) comment operator appears on the same line, as all characters after <big><big>{lamp}</big></big> are ignored.		'''Note:''' The '''<big><big>{diamond}</big></big>''' operator <u>cannot</u> be used after a [[lamp]] (<big><big>{lamp}</big></big>) comment operator appears on the same line, as all characters after <big><big>{lamp}</big></big> are ignored.

	==~~Example~~==		'''Also note''' the '''<big><big>{diamond}</big></big>''' operator represents an <u>exception to the rule</u> that APL's interpreter executes from right to left, since the ''leftmost APL statement'' is executed BEFORE the adjacent APL statement after the next '''<big><big>{diamond}</big></big>''' operator and so on. Each APL statement is executed sequentially '''as if''' listed on multiple lines. The '''<big><big>{diamond}</big></big>''' operator also helps ''condense'' APL code since fewer ''visual'' lines will contain the same amount of APL coding - and in many instances it ''can result'' in cleaner, or easier-to-read-and-understand APL code.
	In ~~this~~ example, the variable K is tested to see if it is greater than or equal to 1. If the test fails, k is set to 1.<br/>
	:<code><big>{goto}(k{ge}1)/Xr {diamond} K{:=}1<br/>Xr:</big></code><br/>		==Examples==
			In the first example, the variable K is tested to see if it is greater than or equal to 1. If the test fails, k is set to 1.<br/>
			:<code><big>{goto}(k{ge}1)/Xr {diamond} K{:=}1<br/>Xr:     ⍝This branch/goto Label is deliberately placed <u>first</u> on its own line!</big></code><br/>
	It is the same as		It is the same as
	:<code><big>{goto}(k{ge}1)/Xr <br/> K{:=}1<br/>Xr:</big></code><br/>		:<code><big>{goto}(k{ge}1)/Xr <br/> K{:=}1<br/>Xr:</big></code><br/>

			The following represents more <u>condensed</u> ''':for ... :endfor''' control structure in a user-function than if it were shown in four separate lines:<br><font color=purple><strong>
			<code>
			A←1 3 5 7 ⋄ :for ii :in ⍳⍴A ⋄ A[ii]←A[ii]*2 ⋄ :endfor ⍝Easier to maintain code if segmented well, esp. when surrounded by long code blocks.
