[WWdevel] replacing PGcomplex.pm with Parser/Legacy/PGcomplexmacros.pl

[Michael G. <ga...@ma...>]

Hi Davide,

I'm glad you reminded me about this because I'd completely forgotten  
that there was a new replacement file
for PGcomplexmacros.pl.

I'd like to propose replacing the current PGcomplexmacros.pl  in pg/ 
macros   with the one in

pg/lib/Parser/Legacy/PGcomplexmacros.pl  for rel-2-3-dev    
distribution of PG.

The current version which I've been inadvertently using for my course  
is buggy anyway and doesn't
run the complex variable problems in the Rochester library very  
well.  As far as I know no-one else
has been doing much with complex numbers and complex variables -- I  
expect if they were I'd be
hearing more complaints.  The files look to be completely compatible  
and I'll be surer of that once
I use the new one in my course.

Does anyone see a downside to replacing the the PGcomplexmacros.pl  
file with the one at Parser/Legacy/PGcomplexmacros.pl ?

Take care,

Mike
