I'm still working on the REXX program to reduce the amount of names by programmatically generating any amount of number-names   (instead of having a fixed amount of names in text form). Also note that there appears not to be a consensus on the names of some numbers: Line 42 ⟶ 65: * '''tre'''           also named '''tres''' ~~<br>~~<br>The   '''$SPELL#'''   REXX program makes use of   '''$T'''   REXX program which is used to display text and/or write the text to a file. <br>The   '''$T'''   REXX program is included here   ──►   [[$T.REX]]. <br>The help for the   '''$T'''   REXX program is included here ──►   [[$T.HEL]]. <br><br>The   '''$SPELL#'''   REXX program makes use of   '''$ERR'''   REXX program which is used to display error messages (via '''$T'''). <br>The   '''$ERR'''   REXX program is included here   ──►     [[$ERR.REX]]. <br>The help for the   '''$ERR'''   REXX program is included here   ──►   [[$ERR.HEL]]. <br><br>Some older REXXes don't have a   '''changestr''' ~~bif~~  BIF, so one is included here   ──►   [[CHANGESTR.REX]]. <br><br> ==output== Output when using the input of:   <tt> 373 ordinal </tt> three hundred seventy-third Output when using the input of:   <tt> 373 </tt> three hundred seventy-three Output when using the input of:   <tt> +45 </tt> plus forty-five Output when using the input of:   <tt> 1989 asYear </tt> nineteen eighty-nine Output when using the input of:   <tt> -12.79 </tt> minus twelve point seven nine Output when using the input of:   <tt> $119.63 </tt> one hundred nineteen dollars and sixty-three cents Output when using the input of:   <tt> 3456T </tt> three quadrillion four hundred fifty-six trillion Output when using the input of:   <tt> 4Ki </tt> four thousand ninety-six Output when using the input of:   <tt> 6! </tt> seven hundred twenty Output when using the input of:   <tt> 10dozen </tt> one hundred twenty Output when using the input of:   <tt> 70000000000000... </tt>     (3,000 zeroes total) seven octononagintanongentillion
