4. SIR/XS 32 character names
VisualPQL
Variables
Sub-Routines
Sub-Procedures
Labels
Buffer Names
Filenames
Database Schema
Database Names
Record Names
Variable Names
Index Names
Passwords
Tabfiles & Tables
Families
Members

5. Standard Names 1 – 32 characters Start with alpha Capitalized
Contain letters, numbers, four special characters $ _

6. Non-Standard Names Enclosed in curly braces { }
From 1 to 30 characters (plus braces)
No translation
Any characters
Stored without braces so sort normally

7. Other Syntax Deprecate use of slash Standard variable lists in ()
Needed in schema commands
Optional everywhere else
Standard variable lists in ()
New syntax for TABULATE
TABULATE [[Wafer,]Stub,]Header / OPTIONS
TABULATE HEADER = (EXP) STUB = (EXP) WAFER = (EXP) OPTIONS

8. Standard summary variable list
Variable names or three keywords
ALL All (with regard to INCLUDE/EXCLUDE)
AS Use alternate name
S(1) AS SALARY or S(1) 'Salary‘
TO Creates list of selected variables A to B
end of the list when:
List starts and stops with brackets ()
End of input e.g. next command (not next clause on same command)
Special character - slash / is valid, other may be
Name that is not a variable – if also not valid keyword gives ‘Error 4 Keyword is invalid'

9. New Schema STANDARD SCHEMA RECORD SCHEMA RECORD num,name ‘Label’
Variable definitions
RECORD SCHEMA
STANDARD VARIABLE varname
RECORD num,name ‘Label’
VAR DOC command
WRITE SCHEMA
Writes TO lists
Writes in Variable Order

10. Multiple Data Files Split the .sr3 data file
No overhead for existing single file databases
Split based on serial key ranges
Case structure – case values
Caseless – record type/key value
DATA FILES ‘filename’
FROM () filename
Before any data added
Requires restructure

11. Existing Data Structure
Top Level Index
Other Index Levels
Data Level

12. New Data Structure FILE INDEX Top Level Index Other Index Levels
Data Level

13. ENCRYPT Encrypts data 128 bit encryption BLOWFISH algorithm
ENCRYPT/DECRYPT PQL Functions

14. New PQL Debugger GUI Interface Step through source
Set breakpoints at lines
See values in variables
Set values in variables
Set watchpoints (break when value changes)
Step into/over subroutines

15. Routine to debug PROGRAM/RETRIEVAL/SUBROUTINE DEBUG {= name}
Stores as a subroutine
If name not specified
Real subroutine uses subroutine name
Other SYSTEM.DEBUG
Generates debug source code
Can be useful even if not debugging
Specify NOEXECUTE if just want to debug

16. Run Debugger Choose which module to debug Module starts
Lists source
Lists variables
Look at other stuff
Members/Files/Buffers

17. No Execution Window Deprecated Commands accept character bell
box
cursor
All template commands
display text
erase screen
field input
fill
keypad on
line attribute
line character
mapkey
mouse
refresh screen
sense mouse

18. Improved Recovery Journaling Rewritten Itemize rewritten Roll back
Roll forward
Auto recover
Transaction processing
Incremental Unload

19. Journal Update Record File Header Database Name Before update
Version of Software
Update Header
Data/Schema
Update Level Started
Date/Time Started
Date/Time Finished (for data updates)
User Name
Update Record
Before update
Before delete
After insert

20. Journal Utilities Journal Recover Journal Rollback Itemize Upload
Rolls forward from given place
Journal Rollback
Rolls back from given place
Auto Recover on connect
Itemize
Lists contents (headers)

Creates machine independent text file

21. Journal Processing New PQL commands to process journals Audit Trail
Access to header data
Access to record values
Audit Trail
Other recovery strategies

22. Journal Commands PROCESS JOURNAL JOURNAL RECORD IS
PQL access to record variables
END JOURNAL RECORD IS
END PROCESS JOURNAL

23. PROCESS JOURNAL [FROM = updlevel | START = date [,time] ]
[THRU = updlevel | END = date [,time] ]
[REVERSE]
[FILENAME= fname ] (sr5 is the default)
Return Data
[DATE = varname] [ENDDATE = varname]
[TIME = varname] [ENDTIME = varname]
[LEVEL = varname]
[RECORD = varname]
[TYPE = varname]
[USER = varname]

24. Example program integer*4 jtype
value labels jtype (1) 'Record written‘ (2) 'Before rewrite‘
(3) 'After rewrite‘ (4) 'Deleted record‘
(-1) ‘Data header‘ (-4) ‘Schema header‘ (-5) ‘User header'
process journal TYPE= JTYPE RECORD = jrec level = jlevel FROM = 13
ifthen (jtype gt 0)
. write [vallab(JTYPE)] 'Record Type ' jrec
.else
. write [vallab(JTYPE)] 'Update level ' jlevel fi
journal record employee
write id name salary
end journal record
end process journal
end program

25. Transaction Processing*
Start Transaction
End Transaction (Commit)
Abort Transaction
Journal Based
Rollback on Abort

26. Incremental Unload* Creates Journal of Updates Add to end of Unload
Automatic processing of levels
Automatic restore by reload
Optional separate file

27. XML XML File structure XML Names Text File Hierarchical Tags enclose
Resembles HTML with own tags
XML Names
Begin with character (or _ :)
Case sensitive
Allow letters, numbers - _ : . (No spaces)

28. Example XML <company> <person>
<name>John D Jones</name>
<salary>2150</salary>
<birthday>1956</ birthday >
</person>
<name>James A Arblaster</name>
<salary>1500</salary>
< birthday >1961</ birthday >
</company>

29. XML SAVE FILE Procedure
Standard Clauses
FILENAME = filename BOOLEAN = (logical expression) MISSCHAR = character SAMPLE = fraction SORT = variable,....
Special Clauses
ROOT = 'string' BREAK = variable ( TAG = 'string', ATTRIBUTES = (varname (format) ),...) ELEMENTS = (varname (format) ),...)) DTD [= filename] SCHEMA [= filename]

30. Example XML <company> - ROOT = ‘people’
<person> - BREAK = ( id tag = ‘person’ - ELEMENTS =(name,salary,birthday))
<name>John D Jones</name>
<salary>2150</salary>
<birthday>1956</birthday>
</person>
<person>
<name>James A Arblaster</name>
<salary>1500</salary>
< birthday >1961</ birthday >
</company>

31. SIR Server Similar in concept to SQLServer Machine Independent
Started on network
Waits for users to logon
Process requests
Returns results
Machine Independent

32. Concept Send commands (text) to server Tell server to execute
Carry on or wait
Get status and count of output lines
All output to standard output can go back to client

33. Client/Server Functions
SERLOG(Client,Server_name,Password)
SERSEND(Client_Id,string)
SERSENDB(Client_Id,buffername)
SEREXEC(client_id,wait_factor)
SERTEST(client_id,wait_factor)
SERLINES(client_id)
SERGET(client_id,skiplines)
SERADMIN

34. Client Sample Program Logon Send Request (check error codes)
Get output line at a time
Logoff

35. GUI Improvements New Messages SPIN & SLIDER Controls TREE Control
Right Mouse click
Mouse over
VSCROLL
SPIN & SLIDER Controls
TREE Control

36. Other Features Suggestions encouraged and welcomed
