Hi Robert,
I have all Maxima Windows releases since 5.9.0 installed on my Windows 2000 computer.
The releases since 5.10.0 use gcl 2.6.8 (aka gcl), which is - as you explained to me in a
previous mail - an inofficial cvs version, so gcl 2.6.8 might be different in different Maxima
releases.
The strange behaviour observed by Rene Grothmann occurs only in Maxima's command-
line version in 5.15.0, not in any other versions since 5.10.0 and not in xMaxima or
wxMaxima.
The older Windows versions 5.9.x using gcl 2.6.5 - 7 show an intermediate input label:
(%i1) 10;20;
(%o1) 10
(%i2)
(%o2) 20
I don't know if it is worth to mention and if it does mean anything but the actual 5.15.0
Windows installer was compiled by Andrej and not as usual by Vadim. Perhaps Andrej and
Vadim use different gcl source code.
FWIW
