- Vortex v1.5
- ~~~~~~~~~~~
- An universal accented character converter
-
- Vortex will convert all accented characters common to a pair of
- computers (Amiga <-> IBM-PC, Amiga <-> MacIntosh or IBM-PC <-> Mac).
- Unfortunately, not all accented characters are convertible because some
- computers have an incomplete set of accented capitals; did you know that
- only the Amiga offers a complete set of lower and upper case accented
- characters for most european languages? Naturally, only common characters
- can be converted from one computer to another. For conversions to and from
- the IBM-PC, Vortex assumes that the extended character set is used, although
- this may not be the case for older PCs that use the standard set, which is
- much poorer (only 5 accented capitals). Then, the user may get some graphic
- characters and mathematic symbols instead of certain accented capitals...
-
- The standard ASCII set (0-127), true to its american origin, ignores
- accented characters. This is too bad, because there are only two latin
- alphabet languages without accents: english and ... dutch. So, accented
- characters had to be patched up, and the result was called "extended ASCII
- set" (128-255). Good idea, but every computer came up with its own standard!
- Commodore implemented the international convention codes on the Amiga, but
- was the only one to do so (nice shot anyway, Commodore). In a nutshell,
- Vortex will work for all languages provided with a keymap (danish, finnish,
- french, german, italian, islandic, norwegian, spanish, swedish), and any
- other language using only "standard" accents (acute, grave and circumflex
- accents, plus the tilde and the dieresis), that is, most west european
- languages, and then some.
-
- NOTE: Vortex converts files, but not the diskette format. It won't read
- IBM, Mac or C64 diskettes. You have to copy the file to be processed on an
- Amiga disk. To do so, you can use utilities like DOS2DOS, CrossDOS or
- MessyDOS (Amiga <-> IBM), Mac2DOS or File Transfer (Amiga <-> Mac), or
- Transfer (C64 <-> Amiga). You can also use a modem. Vortex does not replace
- any of the above-mentionned utilities.
-
- USAGE (from the CLI):
- ~~~~~
- vortex source_file [destination_file] -direction [-options...]
- where:
- DIRECTION: -ai/-ia: Amiga -> IBM-PC /or vice versa
- choose one: -am/-ma: Amiga -> Mac /or vice versa
- -im/-mi: IBM-PC -> Mac /or vice versa
- -ca: C64(Traitex) -> Amiga
-
- OPTIONS: -wp: Word Perfect source file
- [optional] -aw: ASCII -> Word Perfect
- -sl/-sl0: Converts line feeds /or keeps them
- -nc: No accent conversion
- -tx: Replace tabs by x spaces
-
- Source and Destination Files:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Parameters between braces are optional; if no destination file name is
- given, Vortex will create one by appending ".vx" to the source file name
- (thus, "yuck" gives "yuck.vx"). Moreover, any of the first three parameters
- may include an AmigaDOS path: thus,
-
- 1> vortex df1:texts/donald.doc ram:daffy.doc -ai
-
- will read in the Amiga ASCII file "donald.doc" from the "texts" directory in
- df1: and create the converted Amiga ASCII file "daffy.doc" in ram:. ASCII
- file conversion selects -sl as default (-sl0 to override it). Another
- example:
-
- 1> df1:c/vortex myfile -ia -wp -t4
-
- will run Vortex from df1:c and read the Word Perfect IBM file "myfile" in
- the current directory, where "myfile.vx" (Amiga WP file) will be created.
- Option -wp selects -sl0 as default. Note that in the above example, option
- -t4 will convert tabs to 4 spaces.
-
- NOTE: To speed up a conversion, copy your source file to ram:. Vortex is
- quite fast: it can convert a 40K file in 10 seconds or less. No wonder:it is
- written in C.
-
- Direction and Options:
- ~~~~~~~~~~~~~~~~~~~~~
- The following parameters (direction and options) must be preceded by a dash
- and they can be in any order or number. You may use many options, or none,
- but you have to use one (and only one) direction. Remember: one direction is
- needed, but options are... well, optional. If two parameters give opposite
- results (ex. -sl and -sl0), the last one prevails.
-
- Directions: -ai -am -ia -im -ma and -mi:
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The first letter designates the source computer and the second one,
- the destination computer. Thus, -ai means Amiga -> IBM-PC.
-
- Direction -ca:
- ~~~~~~~~~~~~~
- Vortex will also convert Traitex files (Commodore 64/128) to Amiga files
- (ASCII or WP). This is a special case because every C64 word processor uses
- its own codes for the accents... Option -ca can convert with unequal success
- other C64 files using screen codes, like PaperClip or Scripsit files, but
- not PETSCII files. (If you don't know what they are, you don't need to read
- this in the first place). Note that the -ca direction ignores all the
- options below except -aw.
-
- Option -wp:
- ~~~~~~~~~~
- Option -wp converts Word Perfect files from one computer to another. Why
- Word Perfect? Because it's the only word processor implemented on 4
- different machines (this, in turn, creates a need for Vortex). Besides,
- it's my favorite word processor... Please note that Prowrite, Excellence and
- Brand X users should save their files with the ASCII (or Text) option before
- feeding them to Vortex if straight file conversion does not work.
-
- Option -aw will convert ASCII files to WP files, but not the reverse,
- because the "Save Text File" option in Word Perfect already does that.
- Likewise, Vortex creates WP 4.2 files (and not WP 5.x files) from ASCII
- files because WP 5.x accepts and converts WP 4.2 files. In short, I kept
- Vortex streamlined and fast by restricting its options to those not already
- provided by Word Perfect.
-
- Option -aw:
- ~~~~~~~~~~
- To convert an ASCII file to a WP file, use option -aw. This option was
- implemented because WP will not load correctly an ASCII file with accented
- characters. Try it and see what I mean. Option -aw selects
- -sl0 as default. The file format may be slightly disturbed, but at least,
- every word is displayed.
-
- Options -sl and -sl0:
- ~~~~~~~~~~~~~~~~~~~~
- Vortex can also convert the line feed character(s), which vary for each
- computer. (simple line feed (LF) for the Amiga, carriage return + line feed
- (CR + LF) for the PC and simple carriage return (CR) for the Mac). Option
- -sl is chosen by default for ASCII file conversions (-sl0 will cancel it),
- and option -sl0 is selected with -wp and -aw options.
-
- Option -nc:
- ~~~~~~~~~~
- With option -nc, source accented characters are left unconverted. This
- option is used with options -aw, -sl and -tx (below) to change the file
- format, the line feeds or the tabs without changing anything else.
-
- example: 1> vortex mystuff -ai -nc -aw
-
- will convert an Amiga ASCII file to an Amiga WP file. Note that direction
- -ia, cancelled by -aw, is a bogus valus, but it has to be there to enable
- the ASCII -> WP conversion process.
-
- other example: 1> vortex ram:myletter df0:myletter -ai -nc
- This line uses Vortex as a simple file copier. Nothing is changed.
- other example: 1> vortex mytext -ai -nc -sl
- This line will change the LF to CR+LF in mytext.vx, and nothing else.
- one last example: 1> vortex blurp -am -t4 -nc
- This line will only replace all the tabs by 4 spaces in blurp.vx.
-
- Option -txx
- ~~~~~~~~~~~
- Vortex can also convert tabs to spaces (1-20), which is handy for texts that
- have been formatted with non standard tab values (telltale sign: when you
- see a scrambled text on your screen). Normally, a tabulation character
- stands for 8 spaces (ASCII) or 5 spaces (WP). Give it a few tries and you
- will become an ace text straightener (and eventually get hired as a ghost
- writer for some politician).
-
- How to use with a mouse
- ~~~~~~~~~~~~~~~~~~~~~~~
- Vortex is a CLI-only command, but it comes with an icon on this disk.
- Double-clicking on "XVortex" launches a Xicon-driven batch file that opens
- a CLI ("endcli" to exit) and prints the instructions. If you copy XVortex to
- another disk, make sure that Vortex itself is copied, and don't forget
- to copy Xicon in your disk's c: directory.
-
- You can program Vortex with all the options you need with batch files, WP
- macros, hot keys or in a directory utility like Disk Master or SID. With DM,
- all you need is the line: c:Vortex %s -ai -wp to convert a WP file from
- Amiga to IBM. Two mouse clicks and look what happens: a cute .vx file
- appears in the file requester.
-
-
- Any comment is welcome.

- NOTE: ASCII files exported to the Mac should not be loaded in MacWrite,
- which uses its own format for text files. MS Word, which uses ASCII
- files, is a better choice.
