The file requester did not display the proper rounded size for files/volumes; this has been fixed (e.g., a 2408 byte file now appears as "3K" which is correct; "2K" was displayed). We appologize for any problems this might have caused.) Introduction ~~~~~~~~~~~~ ANSIEd is an ANSI Screen File Editor. It allows you to easily create and modify a screen of ANSI-style text/graphics on the Amiga [r]. The standard ANSI color set - RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE - and text styles - PLAIN, BOLDFACE, UNDERLINED, ITALIC - are provided, along with some simple editing and drawing functions. THIS IS A DEMO VERSION OF ANSIEd ONLY. IN THE FUTURE, YOU CAN EASILY DISTINGUISH DEMO VERSIONS OF OUR PRODUCTS BY THE 'D' FOLLOWING THE VERSION NUMBER (e.g., V1.0.5D). "Save As" AND "Save" HAVE BEEN DISABLED. AS A RESULT THERE ARE CERTAIN OTHER FEATURES WHICH ARE DISABLED WITHIN THESE FUNCTIONS. HOWEVER, INFORMATION ON THEIR OPERATION IS INCLUDED IN THIS DOCUMENT FOR YOUR CONVENIENCE. TO GET THE "REAL" THING, FOLLOW THE INSTRUCTIONS UNDER "Purchasing". IT IS VERY IMPORTANT THAT YOU READ THIS ENTIRE FILE BEFORE USING ANSIEd. EVEN IF YOU ARE FAMILIAR WITH THE BASIC OPERATION OF THE AMIGA, THERE IS CERTAIN INFORMATION CONTAINED HEREIN WHICH WILL HOPFULLY PREVENT ANY "SURPRISE" PROBLEMS. What is ANSI? ~~~~~~~~~~~~~ Or more correctly, WHO is ANSI? ANSI is the American National Standards Institue. They, along with ISO (International Standards Organization) set various standards in various fields. They are the ones that decide that the number 65 decimal represents the character "A" to the computer, among other things. A subset of these numeric codes, recognized by most computers on the market today, control attributes of the display such as text color and style. On the Amiga [r], the console and the printer devices are most likely to use these "display control codes". The purpose of ANSIEd is to make creation of files with these control codes for screen (console) display simple. Documentation Symbols ~~~~~~~~~~~~~~~~~~~~~ For the sake of space and brevity, the following symbols are used in the remainder of this document to represent certain actions. D-CLK - means double-click the indicated mouse button (LEFT or RIGHT will be indicated). S-CLK - means single-click the indicated mouse button (LEFT or RIGHT will be indicated). FG - abbreviation of foreground. BG - abbreviation of background. When it is necessary to indicate that you need to press a specific key to perform an action it will be enclosed in <> (angle brackets). Examples are <RETURN> to press the large key above your right shift key or <CTRL><J> to press and hold the CTRL key and then press the J key. The arrow or whatever other imagery you have saved under Preferences as your mouse pointer is referred to as the "pointer". Also, since this is the first update to ANSIEd, new items are marked with a (N) symbol to indicate such. Running ANSIEd ~~~~~~~~~~~~~~ If you wish to run ANSIEd from the CLI we suggest you set your stack size at 12000. From the CLI prompt type: 1> stack 12000 <RETURN> Run ANSIEd from the Workbench [tm] by D-CLK RIGHT on the ANSIEd icon or from the CLI prompt type: 1> ansied <RETURN> You can preceed the name from the CLI with the CLI "Run" command to spawn ANSIEd as a task from the CLI. If you encounter a strange lockup error when running the program it is most likely due to insufficient memory. If it seems that you have enough memory then try increasing the stack size to 20000. Use the above CLI format to change the stack to 20000 (instead of 12000) or use the "Info" option from the "Workbench" menu on the Workbench [tm]. In "Info", change the stack from 12000 to 20000 and remember to select SAVE so it takes effect. If you still encounter an error write down any messages that appear and contact me as soon as possible at one of the sources under "Purchasing" at the end of this document. Describe what other programs you were running and your basic machine setup. ANSIEd uses standard Intuition [tm] function calls and behaves according to Intuition [tm] as much as possible. If you run ANSIEd from the Workbench [tm], the icon is set up with the stack size at 12000. Also, a window will open on the Workbench [tm] for error messages. As of V1.2.0, you may find that you need to increase the stack size to 20000 due to the increase in functions of the program. ERRORS: When most any error occurs the display will usually flash. In any event, a message is usually displayed on the Workbench [tm] screen. It is VERY important that you write the FULL error message down if the message indicates a serious problem. This is provided exclusively for quick and easy debugging and, frankly, we believe our system is better than any other that we have seen for this purpose (of course, it doesn't do any good to just write the message down if you don't contact me by mail, phone, or BBS, to tell me - comprende?) Also, if a system requester appears at any time during use, it will push the Workbench [tm] screen to the front with the message. You MUST answer any system requesters that appear for ANSIEd to continue to operate properly. Once responded to, press the <AMIGA><M> keys to move back to the ANSIEd display. This also works for error messages displayed after a display flash; to view the message, press the <AMIGA><N> keys to move to the Workbench [tm] display and error window, then press the <AMIGA><M> keys to move back to the ANSIEd display. The Display ~~~~~~~~~~~ ANSIEd displays a green title bar at the top, a color bar at the bottom with the current FG/BG colors as boxes on the far right of that bar, and the usable screen area (display) in between. As of V1.2.0 you will also notice some additional items in the right side of the color bar. The Controls ~~~~~~~~~~~~ The mouse, serves double-duty in selecting menu items, FG/BG colors, and cursor position. As of V1.2.0 it also handles 2 drawing tools - freehand and box filled/unfilled. When the mouse is just above the color select bar, the LEFT button will allow access to the menus and the RIGHT button access to cursor positioning. When the mouse is within the color select bar, the LEFT button will set the FG color and the RIGHT button the BG color - when the pointer is over a color in the bar, of course. Try selecting some FG/BG colors and notice the two small boxes in the far right of the color select bar change color. One appears over the other, giving you an ordered representation of the currently selected colors. Move the pointer above the color select bar and hold down the RIGHT button. You can examine the few, simple menu items this way. There are keyboard shortcuts for most of them, available by pressing and holding the RIGHT AMIGA key and pressing the key given beside the menu item. These are most useful for quickly selecting text styles from the style menu. With the pointer still above the color select bar (no buttons pressed), S-CLK LEFT button and the cursor will jump to that position for editing. This is sometimes quicker than any of the keyboard cursor movements. (N) As of V1.2.0, you will notice 3 small buttons in the right end of the color select bar (between the color list and the FG/BG color status). These are for selecting the operation mode. From left to right, they are a stylized "N", a squiggly line, and a box (diagonally split half filled, half empty). Here's what they are and how to use them: (N) Normal Tool: This is highlighted by default at startup. S-CLK LEFT on it to deselect any drawing tools and to allow cursor positioning with the mouse without drawing. As long as you hold the LEFT mouse button down and move the pointer the cursor will move with it. (N) Freehand Tool: S-CLK LEFT on this to enter freehand drawing mode. Now when you hold the LEFT mouse button down and move the mouse around in the display area it will draw character "pixels" in the BG color; to draw somewhere else, just release the LEFT mouse button, move the pointer, and hold down the LEFT mouse button while moving to draw. To move the cursor without leaving a "pixel" S-CLK LEFT on the Normal Tool to get back in normal mode. (N) Box Filled/Unfilled Tool: To select to draw an unfilled box, S-CLK LEFT on the box tool. It doesn't matter where you click, just somewhere on the box. To select to draw a filled box, S-CLK RIGHT on the box tool. In either case, the image of the box will change to indicate the mode you have selected. Now, to draw a box: (a) move into the display area and hold down the LEFT mouse button; this defines one corner of the box; (b) while still holding it down move the mouse; you will see an image of a box drawn whose size will change accordingly as you move the mouse; when it is like you want it (c) release the LEFT mouse button and the box will be drawn in the BG color. To resume cursor positioning without drawing boxes S-CLK LEFT on the Normal Tool to get back in normal mode. The white outline of a box that you see while holding down the LEFT mouse button shows the outermost edges of the box that will be drawn later. Don't try to follow the mouse pointer!!! --- follow the white outline. Only one of these buttons can possibly be selected at one time. That is, if you select one it will deselect whatever was highlighted. There is no "Undo" for the drawing tools. We will probably add this to a future version. For now, if you are going to do some "major" drawing, save your work before you make any changes. (In the "Version.doc" file you will notice a warning about entering anything into the lower right corner of the display buffer. You CAN draw in that area safely as long as you DO NOT release the LEFT mouse button while in that area --- you have been well warned.) The remaining keyboard controls are summarized below: SPACEBAR - use to erase or draw a block at a time by properly setting the BG color; also moves the cursor. BACKSPACE - moves the cursor back one character space WITHOUT erasing; the cursor does NOT wrap at the edges. RETURN - moves the cursor down one screen line (in characters) to the left edge. The remaining keys will not work at all or they will produce a character of some sort, rendered in the currently selected FG/BG/style at the current position. The Menus ~~~~~~~~~ ANSIEd has the following items available in the menus (in order, top-bottom, left-right): Project: New - initializes the editor environment to a blank slate. You only NEED to use this if you want to ensure the buffer is (N) clear as well as the screen. As of V1.2.0 this will warn you if you have made changes since the last save and give you a chance to save them. Open - allows you to load a file selected from the file requester. It takes a few seconds to load a complex file so wait for the "snooze" cloud to disappear before resuming. This does NOT ask if you wish to save the current buffer before loading a new file. Save - allows you to save a file under the current file name. The current file name is the same name you used in "Open" or "Save As". Save As - allows you to save a file selected from the file requester. It takes a few seconds to save a complex file so wait for the "snooze" cloud to disappear before resuming. (N) Delete - allows you to delete a file selected from the file requester. A warning will pop up to ask you if you are sure (this is a safeguard function). As of V1.2.0 this does NOT delete an icon (.info) file associated with the file you are deleting, since ANSIEd does not yet create its own icons for files. About - displays version/title/author information. (N) Quit - exits the program. As of V1.2.0 this will warn you if you have made changes since the last save and give you a chance to save them. Style: The four options on this menu, "Plain", "Boldface", "Underlined", and "Italic" let you select the current text rendering style. They have nothing to do with selecting colors. The current style(s) will be checkmarked in the style menu. "Plain" is mutually exclusive. It will ALWAYS reset the text style back to plain text. "Boldface", "Underlined", and "Italic" can be mixed. That is, if you select "Bold", type some text, and select "Underlined", you will get BOLD-UNDERLINED text, not UNDERLINED text. If you wanted text UNDERLINED only, you would select "Plain" and then select "Underlined". Special: (N) ANSI Filter On - select this to turn on an internal ANSI filter for use with the "Open" option on the "Project" menu. During the load, any character outside the plain text range will be ignored. This is useful for loading ANSI files created on other computers or for getting back the plain text from an ANSI file. When the filter is active a check will appear beside this item. It is a toggle-select item. (N) CRLF Line Term - select this to turn on another handy IBM ANSI feature which operates during the save process. Most IBM BBS programs (you did know that many Amiga [r] BBS's are run off IBM equipment didn't you? hey! that's so they can free their Amiga's for those great games!) like their ANSI files to terminate lines in carriage returns [CR} and line feeds [LF]. ANSIEd normally only stores a LF since that's all the Amiga [r] console needs. When this is active a check will appear beside this item. It is a toggle-select item. Loading, Saving, and Deleting Files ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ANSIEd stores its files as compactly as possible. At times, it will only write just enough of an ANSI control sequence as it needs. You can use a regular text editor to embed ANSI codes in your plain ASCII text files before loading them into ANSIEd, but it really isn't necessary. ANSIEd will pick up these codes regardless of the order you enter them but they MUST be VALID ANSI codes...or you just might get a surprise! We would strongly suggest you keep your plain ASCII text files within certain limits: 78 characters per line, 22 lines. When you use your ANSI file later, it will most likely be displayed in a window with a sizing box in the lower- right corner OR be subject to such a line width limit in telecommunications. Obeying this limit in your ANSI and plain ASCII text files should prevent any unwanted scrolling or chopping of lines. Provided that you always follow this suggestion you will not encounter the lower right corner scroll bug mentioned in file "Version.doc". "Save" and "Save As", under the "Project" menu, will automatically store an ANSI reset sequence at the start and end of the file being saved. It is a safety feature we included to eliminate the unwanted color/style changes left over from previous ANSI displays when used with telecommunications software. The ANSI reset sequence is: set "Plain" text style, with FG color as 7 (WHITE) and BG color as 0 (BLACK). "Open", under the "Project" menu, will recognize VALID ANSI codes in any sequence. "Open" is, of course, used to LOAD a file - the purpose of this terminology is to maintain style within the Amiga [r] interface. It is somewhat slow right now but we are considering adding buffering in a future release. You can load a file upon starting ANSIEd from the CLI or Workbench [tm]. From the CLI prompt type: 1> ansied [path/filename] <RETURN> The [path/filename] can simply be a filename alone if the file resides in the current directory you are CD'ed to. Otherwise you should include the path (this includes a drive such as DF0: or a disk name, possibly followed by a directory). Consult any one of several books on the Amiga [r] CLI if you need more help. While it is possible to load a file at startup from the Workbench [tm], I wouldn't advise it at this time unless you know exactly how to setup the icon to do this. We are considering a feature where ANSIEd will save its files with PROJECT-type icons in a future release, whose default tool will be ANSIEd. (N) "Delete" displays the standard file requester and allows you to select a file to delete from disk; since the file requester functions somewhat differently its use is described here. The file requester functions normally as described below EXCEPT: (1) A file MUST be selected. "OK" will NOT function if there is no filename in the file text box (just below the entries list). "Cancel" will back you out however. (2) When a file is selected and "OK" is selected, a delete warning requester will pop up in the top left corner of the program display. (a) "Cancel" will back you out without deleting but will still leave you in the file requester; just select "Cancel" again to exit the file requester if you wish or select another file. (b) "OK" will ATTEMPT to delete the file; it will close both the warning and file requesters; if the delete fails the display will flash, indicating that the delete did not work, and a message to this effect is printed to the error window on the Workbench [tm] screen. The delete will sometimes occur AFTER both requesters are closed - this is normal and should not cause any problems. The File Requester ~~~~~~~~~~~~~~~~~~ The File Requester appears when you select "Save As", "Open", or "Delete" from the "Project" menu. This will be our standard means of requesting a path/file from the user. (N) As of V1.2.0, the file requester was redesigned to make it easier to use and to allow it to fit on a screen of any size and resolution. The previous file requester was too large and would have presented a problem had we required its use on a lo-res display. We think that the new requester is much neater and easier to use. Some new terminology is in order, however, to make description of the new requester easier. First, it is considered that there are 2 types of information listed in the requester. "Entries" are files and directories; "Volumes" are mounted disk units that are in use (including hard drives, recoverable drives, etc.). Path/File Text Boxes: These horizontial boxes appear, one above, one below, the list of volumes-entries. The Path Box (above the list), includes such things as drive names, disk names (volumes), and directory names, and combinations of any of these in that order. The File Box (below the list) only holds the selected filename. Volumes-Entries List and Slider Between the path/file text boxes is a list of items. These will either be Entries (files/directories) OR mounted Volumes (disks), depending on the Volumes-Entries Button selection (see below). Seven (7) are shown at one time, sorted alphabetically; a maximum of 1000 entries or 30 volumes. Also notice the Slider to the right of the list. Use this to scroll up/down through the list or S-CLK LEFT inside the slider box (not on the knob) to flip a page at a time through the list. No arrow buttons are provided since precise positioning isn't necessary and since the file requester does not present a "window" into a larger display. If you do not see any volumes-entries in the list then a non-terminal error has occurred or there was no information. If there is ever a serious error the display will flash and a message will be displayed in the error window on the Workbench [tm] screen. See the section above on ERRORS for more information. Volumes-Entries Button This is a toggle button. Each time you call up the file requester it ALWAYS lists entries first, so this button displays "Volumes". When "Volumes" appears in this button, a S-CLK LEFT on the button will display a list of mounted disk volumes in the list area. When "Entries" appears in this button, a S-CLK LEFT on the button will display a list of files/directories, based on the path currently in the Path Box. Parent Button Located beside the Volumes-Entries button, this will move you back up one level from within a directory towards the root. It will NOT work (1) if there are no more levels or (2) you are looking at a Volumes list. As of V1.2.0 the "ghosting" has been removed since it didn't completely render properly. OK/Cancel Buttons The "OK" button accepts your selection and the "Cancel" button rejects your selection. It is assumed that you know what selection incurs. (N) As of V1.2.0, please see the description of the "Delete" function above for information on how the function of the requester changes when using "Delete". You will also notice several enhancements to the display of the file requester: (N) * In the Entries list, DIRECTORIES appear in BOLD type in one color. FILES appear in NORMAL type in another color. (N) * When a selection is made from the list it is not highlighted. The selection will appear appropriately in the path or file box. This is changed due to improper rendering of the display during real-time updates of the requester. (N) * FILES and VOLUMES have a number which appears to the far left of the list. First, some explanation of this number: a letter (B, K, M, or G) appears farthest to the right beside the number; B for Bytes, K for Kilobytes, M for Megabytes, and G for Gigabytes. Thus 64B is 64 bytes and 173K is 173 Kilobytes. For FILES, this number/id is the size (rounded) of the file, or the amount of space USED on the disk. For VOLUMES, this number/id is the amount of space FREE on the volume; this would seem to be more useful to me than the amount of space used. If your RAM Disk (RAM:) is available the amount of space USED is shown, since the RAM Disk is ALWAYS full. To remain compatible with V1.2 of the system the RAM Disk is called RAM: to avoid crashing the machine. This bug is fixed in V1.3 of the system but we will leave it like this until most people are on V1.3/V1.4 of the system. (Incidentally, did you know that the Terabyte is 1 trillion bytes [or 1.0E12]. A Petabyte is 1 quadrillion bytes [or 1.0E15]. An Exabyte is 1 qunitillion bytes [or 1.0E18]. Unfortunately, the current definition on the Amiga [r] seems to be limited to about 4 Gigabytes...at least the entry size is defined as a 32 bit number, so 2^32 = 4,294,960,000 [approx]. Now when we get our 64 bit systems we can reach just over 18,446,700,000,000,000,000 or about 18 Exabytes; this is good Trivial Pursuit stuff!) Development Tools ~~~~~~~~~~~~~~~~~ ANSIEd was written entirely in Modula-2 using Release 3.1 of Interface Technologies' M2AMIGA Modula-2 Development System for the Amiga [r]. Graphic images were designed using DPaint-II, ZapIcon, and ILBMDump. Final Comments And Suggestions From The Developer ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ While typing, the cursor will wrap to the next line. CAUTION: Again, please do NOT enter a character in the lower-right position as that will cause the screen to roll up. I've warned you for the last time NOW! There is no insert/overstrike mode. After creating several displays, I cannot understand why insert would really be needed. Text/graphics ALWAYS write over any material under them. The author of another ANSI editor proposes an insert/overstrike in his next release but it seems a waste of time and a real hassle when trying to create complex graphics. Along with the changes mentioned throughout this document that will be provided in a future release, I also plan to include the IBM Graphics Character Set. This will provide some very neat looking boxes and other graphics that are impossible with the Amiga [r] character set. The best colors for text display have BG set as 0 (BLACK) and FG set as 2 (GREEN), 3 (YELLOW), 5 (MAGENTA), 6 (CYAN), or 7 (WHITE). Remember that the ANSI reset sequence "Plain" FG WHITE on BG BLACK, will automatically be written at the start and end of a file when it is saved. Note that the null-space bug is fixed as of V1.2.0. However, there still seems to be a problem with some files. We recommend you ALWAYS 'Type' your files from the CLI to check them for proper display. Don't expect them to look exactly the same since the Workbench [tm] is only 4 colors, but lines should wrap properly, and, in some cases, you may notice that colors don't seem to turn off. I've checked and re-checked this and cannot find the problem. The codes are THERE. My guess is that space characters (32 decimal) cause these codes to "stick" sometimes and on IBM, the character 255 decimal usually prevents this. When we are certain that we have found a way to incorporate this into ANSIEd, regardless of the machine or font, this fix will be added to ANSIEd. There is a temporary solution but it varies in how it works: set both FG and BG colors to black and fill one or more spaces along the entire rightmost edge of your image; you may want to save the file and check it from the CLI to see if this made any difference. I've had some files where one space would work, sometimes 2, and once even 6 were needed for some reason! There seems to be no pattern. When you load your own plain ASCII text files for adding color/style changes, you will note that you get "Plain" FG RED on BG black text. That's a bit hard for some people to read. To fix it, just immediately save the file and then reload it. The ANSI reset sequences will be saved and when you reload the file you'll have "Plain" FG WHITE on BG BLACK - much more readable! If you are using ANSIEd to create graphics for an Amiga BBS that runs on IBM equipment, PLEASE use the new menu items V1.2.0 provides - ANSI Filter and CRLF Line Term. You should save ANSI files with CRLF Line Term ON. You can quickly fix any plain files using this too. Just load them into ANSIEd, make sure CRLF Line Term is ON, then save them (under the same name or a new name). You should then load the ANSI file into a text editor such as MicroEMACS and remove the "^[31;40;0m" sequence from the beginning and end of the file; leave the "^M"'s - that's part of what CRLF Line Term did to fix your file. If you have further suggestions for new features or bugs/problems with this version contact me at one of the sources below. I've enjoyed writing ANSIEd (well, for the most part - except when it got rather stubborn and persnickety) and hope you find it useful as well. If you do, why not get the "REAL" thing? See "Purchasing" below. I will continue to release updates to ANSIEd as long as I receive a fair amount of interest and compensation. Being a certified Commodore-Amiga developer, as well as having two college degrees in computer information systems, I simply cannot afford to "do it for fun" all the time. And as the Amiga [r] seems to be the one place where I have this so-called "experience" that every employer wants, it looks like I'll have to make my living off the Amiga [r]. Don't assume "the other guy" will help me out - do it for yourself. After all, how would you like to work for 2 months and then not get paid for it? Think about it. Purchasing ~~~~~~~~~~ Prices for any older versions of ANSIEd are no longer in effect.
