<br><br>'''Error?'''
<br><br>The REXX program (below) produces an extra blank line in the output.
<br>This extra blank line can't be noticed easily (or not at all) when just viewing the output,
<br>but if the output is re-directed to a file, the extra blank line then becomes obvious.

<br>with an extra blank line equal to a 19-line program?

: It doesn't for me.
: The original program contains 53 lines of code (there's a new-line after the last end clause), as does the result; passing the original program and its output through both <tt>diff</tt> and <tt>wc</tt> confirm this:
