Re: %EOF - more on GOTO

[Bob Spinks <rspinks@xxxxxxxxxxxxxx>]

What about n-way(pipeline/scalar) processing using multiple chips(up to 12)
on the 720 box. 

Conditional branching(i.e. GOTOs,CABs,etc.) clogs up the pipelines due to
prediction
algorithms which must be used for the branch instructions.

Optimization is achieved when all pipelines are full and an instruction is
completed with each 
cycle. This is impossible when branching is used in the pgm.

Information on this subject can be gotten from Soltis' book "Inside The
AS/400".

One last vent, GOTO is synonomous for Spaghetti!
