Speaking of MS-DOS memory consumption, I just (finally) picked up a copy
of PC-DOS 1.10 a few days ago. The manual includes these enlightening
comments with regards to memory requirements:

"Increased Memory Requirements

 First, DOS Version 1.10 is about 250 bytes larger than Version 1.00 and
 BASIC and BASICA Version 1.10 are about 200 bytes larger than their
 Version 1.00 counterparts. In general, this should not affect any of the
 applications that you have written and already run with Version 1.00.
 Should you encounter the rare case of having one of your applications
 "not fit" with Version 1.10, it may be necessary to "trim" your program
 to run with Version 1.10. Although we've made every effort to keep
 things from growing, some growth was unavoidable."

Now, I wonder... was IBM speaking for Microsoft when they talked about
"effort to keep things from growing"? :)
