Revision 1.2, Mon Feb 7 03:14:39 2000 UTC (24 years, 7 months ago) by noro
Branch: MAIN
CVS Tags: RELEASE_1_1_2 Changes since 1.1: +345 -40
lines
Added a switch "fortran_output" in ctrl().
If it is equal to 1, polynomials are displayed in fortran style
(x^2 -> x**2 etc.).
Numbers and keywords of arbitrary length can be accepted by the parser.
