22.3.8.3 Tilde P: Plural</H2> <P>
|

If <I>arg</I> is not <A REL=DEFINITION HREF="f_eql.htm#eql"><B>eql</B></A> to the integer <TT>1</TT>, a lowercase <TT>s</TT> is printed; if <I>arg</I> is <A REL=DEFINITION HREF="f_eql.htm#eql"><B>eql</B></A> to <TT>1</TT>, nothing is printed. If <I>arg</I> is a floating-point <TT>1.0</TT>, the <TT>s</TT> is printed. <P>
|
|
<TT>~:P</TT> does the same thing, after doing a <TT>~:*</TT> to back up one argument; that is, it prints a lowercase <TT>s</TT> if the previous argument was not <TT>1</TT>. <P>
|
|
<TT>~@P</TT> prints <TT>y</TT> if the argument is <TT>1</TT>, or <TT>ies</TT> if it is not. <TT>~:@P</TT> does the same thing, but backs up first. <P>
