==$SPELL#.REX==
This is the '''$SPELL#.REX''' (REXX) program.
It is invoked (called) from other REXX programs to spell numbers with various options, including spelling the number as an ordinal number.
The help for the '''$SPELL#.REX''' REXX program is included here ──► [[$SPELL.HEL|$SPELL#.HEL]].
The '''$SPELL#.REX''' REXX program makes use of '''$ERR.REX''' REXX program which is used to display error messages (via '''$T.REX'''); error messages are displayed in red if the terminal supports color.
<br>The '''$ERR.REX''' REXX program is included here ──► [[$ERR.REX]].
The '''$SPELL#.REX''' REXX program makes use of '''$T.REX''' REXX program which is used to display text messages.
<br>The '''$T.REX''' REXX program is included here ──► [[$T.REX]].
