Subject: Re: Fortran To Java


i have not used F2J but you can always convert fortran code to java code 
manually fast. i also donot trust automatic converters because they either 
generate larger code or they dont compile right at all. i used matlab to C 
converter before and automatic serial to parallel code converters. in all 
cases, the performance, compilations were very big problems. so, i suggest 
the longer but the safest way of converting manually.

thanks,
