-
- By now, I have my new Psion 3 for more than a week and am realy impressed
- with it (external) design and its operating system and
- applications. To learn its programming environment and to
- sort my phone book, I have written Sorter which its sorting core
- is based on the example in the Programmer's Manual
-
- Sorter is a Psion 3 application to sort data files (such as phone books).
- It sorts the records by the value of their first field (which in
- the case of a phone book, contains the Name field). Case differences
- are ignored.
-
- To install Sorter,
- 1. copy the file sorter.app to the applications directory \app
- 2. Install it using the <Psion>-I key in the System screen.
- This will add the Sorter icon to the icon list and below it
- you wil see the list of avialable data files (same list as
- in the Data icon)
-
- Run sorter in the same way that you run Data (for example,
- point on one of its files and press Enter). Sorter will first
- check if they file is already sorted (usefull for Flash SSD) and if
- not will sort it.
-
- If you want to compile Sorter, copy sorter.opl to \opl and sorter.pic
- (an icon)to \opd and compile sorter.opl.
- If you want to run it as .opo program
- (rather than .opa), comment out the 'app' section in the begining of the
- file and compile it. The code in open:() procedure suppose to handle the
- case where the command line parameters cmd$() does not exist (in this
- case, it opens a dialog box and enables to select a file).
-
-
- Notes
- 1. Sorter will refuse to sort a file activated with the <psion>-n (New)
- function as the file does not exists.
-
- 2. If the file to be sorted is opened by another application, Sorter
- will show a message and will refuse to sort it. To sort the
- file, close the application first.
-
- 3. Sorter is Freeware and is supplied AS IS.
- I have checked with with several data files and trust it
- enough to sort my own phone book. Before using it the first
- time, have a backup of any important data).
-
- 4. Any comments (including sppellling ;-) ) are welcomed.
-
- 5. When sorting, the amount of data written to the disk is of the
- same size as the original (and the sorted) file. On ramdisk
- that's not a problem as the old area is reclaimed automatically
- (no need to Compress after the sorting) when the file is closed.
- On a Flash SSD (which I don't have [yet]) the memory is reclaimed
- only when the drive is formatted, and thus, if the file size is N
- bytes, after the sort you will have less N bytes free. If an
- already sorted file is sorted again, Sorter detects it and does
- not sort.
