Think `tools'.

-1) To be able to give grep (also awk, etc) a record size 
-which it would use instead of newlines.  

Use `dd | grep'.

-2) To be able to specify a field range (ie columns 20-30) for the 
-program to search - instead of the entire line/record.  In addition it 
-should be posible to specify several fields in one grep.

Use `dd | cut | grep'.
