-
- Which RISC OS?
-
- !SWIRef has only been tester£d with RISC OS 3.1, but should work with
- any version. That is, I have tried to avoid using any OS dependant
- routines, and have even tried to check for RISC OS 2, so that !SWIRef
- doesn't make any calls to DragASprite. If you have any problems, let me
- know what the error/problem was and where and when it occured, and I'll
- see what I can do. See the end of this file for how to contact me.
-
- What is !SWIRef?
-
- !SWIRef is a program for converting SWI names, eg OS_File, to their
- equivalent numbers, eg 8. This is useful for 2 reasons:
-
- 1) It makes programs smaller, as they have a 5 figure number instead of
- huge string.
-
- 2) It can speed up the execution of a program, as the computer converts
- the SWI name to a number when it executes, so this removes the need
- for that, and the computer can execute the SWI directly without
- having to spend time looking the name up first.
-
- !SWIRef can convert SWIs in three different ways:
-
- 1) Interactive SWI Conversion.
-
- To use interactive SWI conversion click SELECT or ADJUST on the !SWIRef
- icon on the iconbar to open the main window. When this window is opened
- the caret will be in the SWI number writeable icon. To move the caret to
- the SWI name writeable icon either click in it with SELECT or ADJUST, or
- use the ⇧ or ⇩ cursor keys.
-
- By default you should enter SWI numbers in decimal, but this can be
- changed to hexadecimal via the options window (click on Options, or
- select Options... from the iconbar menu). The three letters in brackets
- in the main window's title bar show the current setting, either (hex)
- for hexadecimal or (dec) for decimal.
-
- To convert a SWI number to its equivalent name, enter the number in the
- appropriate base (hex or dec) in the SWI number writeable icon, and
- either press <RETURN> or click SELECT or ADJUST on the Convert icon.
-
- To convert a SWI name to its number, enter the name in the SWI name
- writeable icon, and either press <RETURN> or click SELECT or ADJUST on
- the Convert icon. NB - The SWI name is case sensitive.
-
- Note - When you click on Convert, !SWIRef converts the name or number
- according to which icon owns the caret at the time. If neither icon owns
- the caret !SWIRef will attempt to convert the number.
-
- 2) Convert SYS names to numbers in a BASIC program.
-
- When 'Convert names to numbers' is selected from the options window, the
- text 'Name->Num' will appear under the icon on the iconbar, then you can
- drag a BASIC file to the !SWIRef icon to convert all the SYS commands
- (BASICs version of SWI) from names to numbers. When you drag the file to
- !SWIRef it is loaded and converted. When the conversion is finished a
- savebox will appear. The converted file is the saved in the normal way.
- The Save Report icon will save a report for the conversion if it is
- ticked. This report is saved to the same directory as the converted
- file, and has the filename ConvReport. This report tells you how many
- SYS commands were in the file, how many were converted, and how many
- were not recognised. It also provides a list of any unrecognised SYS
- commands.
-
- Note: Conversion of files can take quite a long time. The hourglass
- percentage gives some indication of how the conversion is progressing.
- To abort the conversion at any point press Escape.
-
-
- 3) Convert SYS numbers to names in a BASIC program.
-
- This works in the same way as Convert names to numbers, and is selected
- via the options window. Due to the way I've written it, this routine
- takes about twice as long as the previous one, as it initially scans
- through the program to allocate memory for the conversion. When it is
- scanning the program, the hourglass counts down from 99 to 0, and then
- back up to 99 when it is converting the program.
-
- Again, to abort at any stage press Escape.
-
- Reasons for Unrecognised SWIs/SYSs
-
- For simplicity I will just refer to SWIs, as they are technically
- exactly the same as SYSs.
-
- SWIs are usually unrecognised for one of two reasons:
-
- 1) The name has been misspelt - SWI names are case sensitive.
- 2) The module that provides the SWI is not resident in memory.
-
- Anything Else.....
-
- The above is (I hope) a guide to the use of !SWIRef. If you have any
- immediate problems then !SWIRef does support interactive Help via
- Acorn's !Help.
-
- If you have any problems, comments, bug reports (and there are probably
- still several in there), or would like more information about BubbleSoft
- or its sister (or is that brother) company Wabbit, then I can be reached
