I have this legacy code base (Compaq PERL), about 1500 lines of code, that I need to port to windows. I wanted to use gnu PASCAL (which I have installed and have working). I have already got our assembler (HP 64000 8051) off the VAX and on to Windows (KEIL 8051). The director of Software engineering would like to get all products off the...

Complete slices are stored consecutively as a 256 x 256 array. Pixels consist of 2 consecutive bytes making one binary integer. Data taken o...

I haven't found any recent books like that, but I would expect that there were some good ones written in the 1970s and 1980s, when whole applications were still written in assembly. The architecture used sho...
