DOUBLE DATA is a Psion Series 3a/3c/3mx Data programm 

Double Data can show up to 32 fields per page, in a one ore two collum
mode. In one collumn mode you can switch via cursor up and down between
the two pages. 
In line view mode, up to 19 records to 10 fields can be shown.

Additional you are able to create calculated fields and a total sum
over selected fields.

<,> searching (time, date, numeric)

Fast AND/OR searching

Three Date or time or text stamps at specific actions can be used. 

Language can be selected between german or english (Helpfiles are included).


Double Data do have some restrictions for DBF files:
1) content per field limited to 250 characters
2) do not use tabs (displayed as character!)
3) do not use shift enter(displayed in same field, limited by spaces)
4) 30 characters for labels
5) possible problems with some files created by JBDATA
6) slower opening of JBDATA files with less than 32 fields
7) no line wrap

Double Data should NOT be used for long notes!
Double Data was written to use with files you use at the desktop PC with
DBASE, APPROACH or ACCESS (without memo fields). 

INSTALL DOUBLE DATA ON YOUR SERIES 3A/3C:

A) WINDOWS:

Start PSISETUP and choose DDATA.CTL

B) DOS

1. Copy DDATA.OPA in any /APP directory
2. Create a subdirectory called /DDATA in any APP/ directory
3. Copy DDATA.DDD, DDATAENG.RSC(engl. Helpfile) or DDATAGER.RSC(german helpfile)
   in the /APP/DDATA directory
4. Install DDATA.OPA with PSION-I
5. To be able to sort, you need to copy JBSORTB.IMG from J. Boyce 
   into M:\img\


HISTORY:

Version 1.0:
The inbuild DATA-Application is not able to show more than 13 fields per page and
a lineview is missing. For databases with more than 30 fields I had to scroll up 
and down so the overview was lost.
For this reason I programmed DOUBLE DATA. Also a line view was implemented
(in Ver. 1.0 only for the first 8 fields). Some times I needed to calculate 
time differences or prices or a total sum over some searched fields, so DOUBLE DATA 
is able to do so.


Version 1.1:
A few bugs about the actual position in the database after searching are corrected.
Memory consuming when editing is minimized.
In Line view now you can scroll left and right, and all fields will be shown.

Version 1.2:
Exporting found records, all records or an empty database (only with labels)
Copy Record: to duplicate a record, if you only have to do a few corrections for a new entry.
Compress file

Version 1.3:
Now you are able to search for dates(or time)  before ore after a given date
Search & Replace: You can search in one field and replace in another one 

Version 1.4:
Sorting big databases in OPL is very slow. An extern Sort-programm (APP) can be linked to Double Data.
English and german menus and dialogs are in an editable *.DDD file.

Version 2.0:
Deleting of all found records. Stamp at new or edit a record (time, date, text, counter).
Save as: now you are able to add found records to an existing database.

Version 2.1:
Save as: <, > searching; active record can be added to an existing file
Stamp: 	Now three fields can be used for stamp; "copy of record" added;
	 if counter is used, actual counter is saved in an ini-file
Search & Replace: choice between replace all and replace only searchstring

Version 2.2:
Save as: deleting of exported records added
No error at sorting small files with extern sorting-programm (delay: file open/close) 
DDATA.OPA file size reduced

Version 2.3:
Few bugs at "Delete found records" eliminated
Table view: now number of collums can be choosen from 1 to 10

Version 2.4:
If all data were exported, an error in line view occured (eliminated).
Faster <>searching

Version 2.4e:
Labels of some 3c DBF files coud not be read (find labels routine updated)
Initscreen added (view at startup can be set to line view or page view)
Embedding of J. Boyce's JBSORTB.IMG

Version 2.5:
Faster startup (new find labels routine)
New: "Edit labels", labels can be changed and added
New: "New file", now you are able to create a new file

Version 2.5c:
Bugs in "New file" eliminated
Solved problem with files which have less than 32 fields, created by JBDATA  

Version 2.5d:
AND/OR searching added!
AND/OR found records can be exported and deleted, reports can be created.

Version 2.5e:
Only a few little bugs removed.
