Psion Setup (c)1996 PROTRONICS USA 404-351-1055 CompuServe 71021,1544

Setup is a system used by all Protronics apps to store and retrieve 
preferences. If run directly it will open SETUP.DBF in the Data app.
Here you can change defaults or delete those for apps you don't use.

Developer's Kit

Setup was created to standardize user defaults & encourage users to
register with you. By storing all OPA/OPO defaults in one DBF file,
total files are reduced, memory is saved, and setup is simplified.
Development is faster as code is reduced and less memory is needed
during runtime. If the user defaults are damaged or deleted, SETUP
will automatically rebuild SETUP.DBF from app defaults passed by the
calling program.

SETUP.DBF can contain defaults for dozens of apps making them easily
accessible to the user. By tracking registration codes, users are
strongly encouraged to register, meaning more money for developers.
The only thing we ask in exchange for the SETUP.OPO code is for you
to send us your app when it's done. We will test it & provide feedback.

Installing Setup

1) Copy SETUP.DBF into \DAT  (mark as Hidden*)
2) Copy SETUP.OPO into \OPO  (mark as Hidden)
*Optional (Setup will recreate SETUP.DBF if damaged or missing)

To mark SETUP.OPO as Hidden:
Find the OPL balloon (press Psion-J to install RunOpl)
Hilite SETUP.OPO, press Psion-T, and set Hidden to "Yes"
See other .TXT files for more instructions

Notes

You may use Setup for your own development, but remember other apps use
SETUP.DBF to store defaults too. Please keep to the routines in SETUP.OPO 
and let us know if you need added functionality.

If you have suggestions, ideas, or install trouble please let us know.
Send us a $25 registration fee, and you will receive all of our Psion
Utils via e-mail over the Internet (uuencoded) or CompuServe (zipped).
You'll be on our list for new releases & receive free updates for life. 

International users may register via CompuServe (GO SWREG  ID#: 7768)

SETUP.OPO contains 4 functions:

OpenF:(App$)
App$=Application Name

Opens SETUP.DBF (uses logical D so A, B, & C are free)
Displays Copyright notice & Licensee
Checks if registered
If Not, allows user to enter name & code or use for a trial period
If the app config is missing, a new one is created
Reads user defaults into memory

IO$:(Var$,Data$,io%)
Var$=Name of Variable
io%=0(read) or 1(write)
if io%=0, Data$=App Default
if io%=1, Data$=User Default
IO$ searches for the variable name
App default is returned if io% is 1 or Var$ is missing
User default is returned if io% is 0 and Var$ is found

CloseF:
Writes user defaults back to file
Closes SETUP.DBF
(If no save is necessary, use CLOSE instead of CloseF:)

OpenD:(App$)
Opens SETUP.DBF using DATA, jumps to App, allows user to edit profile,
and returns the process ID.


Sample App:

PROC MAIN:
	GLOBAL Remind%, Code%, User$(25), Drive$(7), App$(12)

	Init:

	PRINT "Files:",Drive$
	IF Remind%
		PRINT "User:",User$
		PRINT "Code:",Code%
		ENDIF

	PRINT chr$(10);"Notice Files =",Drive$,"not M:\WRD\"
	PRINT "Try changing the data in SETUP.DBF and running again"
	PRINT "Press a key..." :get
	OpenD:(App$)
	UNLOADM "Setup"
ENDP

PROC Init:
	GLOBAL Vars$(16,60)
	app$="MyApp"
	LOADM "Setup"
	OpenF:(App$)

	REM Write variables (forces defaults)
	Drive$= IO$:("Files","M:\TXT\",1)
	Remind%= IO$:("Remind","On",1)="On"

	REM Read variables (defaults are included in case missing)
	User$= IO$:("User","Unregistered",0)
	Code%= VAL( IO$:("Code","9999",0))
	Drive$= IO$:("Files","M:\WRD\",0)

	closef:
ENDP
