Changed the nightly build section to user a environment variable for the user name when connecting to sourceforge. Old user name that was being used was Boisy's and really ment that only he could do the nightly upload. With this change should make it possible for anyone who has write access to the web side of the NitrOS-9 project the ability to upload the zipped disk set. The environment variable used is SOURCEUSER and should be set in your login script on your system.

               TTL       VDG Interface Definitions

* Notes:
*
* All offsets from 'U' (address of device memory area)
* (see p. 6-9, technical reference: U=start of driver data memory
* NOTE: There is LOTS of stuff which is only used once, and some which
* is not needed.  Here's a list of the un-needed, and un-used (other than
* once)
*
* It would probably be benificial to patch VDGint to fix these problems,
* unless anyone else has ideas as to why VDGint is doing things this way.
*
* Un-needed
* VD.EPlt1  - (2) set to VD.NChar, and then read only
* VD.EPlt2  - (2) set to same as VD.EPlt1, and then unused
* VD.Chr1   - (1) set to same as VD.CChar, and then unused
* VD.PlFlg  - (1) initialized to $08, and unused
*
* Un-used
*
* $1D       - (1) end of SCF memory requirements
* VD.Strt1  - (2) CLRed, and then read (LDD) - left as $0000
* $24-$2B   - (8)
* $33-$34   - (2)
* $7E-$FF   - (130)
*
* Total of 22 (150 in whole page) bytes unneeded or unused.
