Re: Making a List

LOL! What a wonderful comparison.

The first thing that comes to mind is that almost all production Vax systems 
today run on a emulated platform called Charon, which
means they use PC hardware.

Secondly, you can access the underlying machine as easily on a Vax as on a 
mainframe, and unlike on a AS/400. This sounds like a
minor difference to a COBOL programmer, but it really isn't.

Vax use ASCII terminals and serial/telnet connections, AS/400's use block mode 
terminals

Vax uses a stream based DASD format, AS/400's use a record based DASD format. 
(natively speaking, Vaxes use RMS which gives a record
based DASD, and 400's can handle stream files of course.)

Most common language on a Vax is Macro-11, and it supports system programming. 
Most common language on a AS/400 is RPG, and it does
not support 'system' programming in the sense we use it on a a Vax or mainframe.

Hope that helps.
