This is the third version of this zap. The original did not correct for
|
||
different Prolok fingerprints and the DB3Zap & DB3V2 "Unp" file was too
|
||
long and clobbered the initialization code. The Unp must not be longer
|
||
than 256 bytes. L.Ferris 11/2/84 11/21/84

|
||
There are two version of Dbase III version 1.00. Ashton/Tate states
|
||
they did not change the version or modification number because no code
|
||
was changed. That is probably true. It was Prolok that had to change
|
||
THEIR code. It was re-issued as a result of Prolok problems with IBM
|
||
ROM version '76 or earlier. The two versions may be identified as
|
||
follows:
|
||
|
||
Edition 1 Edition 2
|
||
|
||
Dbase.Exe size 112,720 Dbase.Exe size 117,072
|
||
Gives Version Date at prolog Gives no version date.
|
||
6.6.84 10.4.84 etc "IBM/MSDOS" message only
|
||
|
||
AT the .Quit command, AT the .Quit command reminds
|
||
simply returns to DOS you to backup your files.
|
||
|
||
Use Db3v21... files Use Db3v30... files
|
||
|
||
|
||
I include both versions of the unprotect fix here. You must choose the
|
||
one that fits your version.

|

|

for their time, information and patients. And to all of you who have
|
||
tried these zaps without success, thank you for your patients. I do
|
||
believe we've got it knocked this time though.
