Use the /ed=+ switch to create this kind of external reference. - helpC will notify of an error if a .PARAGRAPH is not closed at the end of a topic. - OS/2 IPF links are now generated with the res= attribute, instead of the refid= attribute, so they can be compiled to .HLP and .INF files. - Added error processing. Use the /EL=x switch, or the .ERRORLEVEL x HDF command to set the error level. Using this feature the helpC compiler can perform one of the following actions in cases of non-existent links : No Check - (Default) - No action is taken. Trap - The link is replaced to a special topic named ERROR. Strip - The link is replaced by the Text part only. Delete - The text and link parts are deleted. Abort - helpC will abort with an error message, indicating the line number. Please refer to the helpc.doc file for more discussion of this feature. - Added the .ALIAS command to the HDF syntax. Use this command to give topics/popups alias names. This command can be very useful when HLPDK is the target of an incremental compiler. - Added popup support for the OS/2 IPF target. .POPUPs are translated to :fn entries from this version. - Added keywords support to the OS/2 IPF target. Topic Keywords appear in the IPF index as level 1 indexes (:i1), with the topic titles as level 2 indexes under them. (:i2). - Group Names are 30 characters from this version, compared to 15 in the previous versions. - helpC handles long target lines better from this version. In previous versions helpC could support only lines that were of 253 characters long of target code. From this version helpC has a sliding output buffer that allows longer target output lines. - ALIGN text attribute command name fixed. (It was mis-spelled in previous versions). - The scroll box in the help engines was fixed to scroll correctly when the downarrow and uparrow keys are used. ******************************************************************************* * Introduction * ******************************************************************************* The Help Engine Development Kit is a system that allows you to create hyper-text database help systems with topics and hot links, using a simple text editor and the help compiler. The help databases can be distributed (free of charge) with the HELPENG or HE help engine display programs. The help database format is release to the public domain, if you own the Paradox Engine you can use the help databases with your own programs. Borland Pascal Users can purchase the Help Engine Source Code even for Applications that do not use the paradox engine, using the Native Mem format. The helpC compiler that is part of this development kit includes the ability to create Windows Help source files from the same source the DOS help sources are created!. Write your help once, and create help databases for DOS, Windows, OS/2 and DESQview/X ! From the same source you created your hypertext database, you can create a text document with automatic table of contents, glossary and index sections! Using the RTF target you can prepare your professional documentation by generating word processors documents, all from the same source! Contact ISoft D&M if you want to purchase the WINTEXT UI library for Turbo Pascal programs, and use the help engine window in your PASCAL programs. ******************************************************************************* * Setup * ******************************************************************************* Copy the files in this package to a directory of your choice. ******************************************************************************* * Quick Start * ******************************************************************************* From the command line enter HELPC HELPDEMO to compile the demo help database. After the compilation process is ended, enter HELPENG HELPDEMO to browse the demo help database. If you want to compile for windows : from the command line enter HELPC HELPDEMO /W31 and after that HC31 HELPDEMO (HC31 is the Microsoft Help Compiler) from windows, open the HELPDEMO.HLP file from the windows help engine. (Notice - if you do not have the HC help compiler from windows, we have included a compiled version of HELPDEMO (HELPDEMO.HLP) so you will be able to feel the quality of the output that can be generated, and decide if you want to purchase the HC31 program (Included with the SDK, BC++, TPW, BP and probably some other packages), or download it from one of the sites Microsoft had uploaded it to). If you use windows 3.0, or want your help file to be compatible with winHelp 3.0 use : HELPC /W30 HELPDEMO HC HELPDEMO To compile for THELP use : HELPC /TH+ HELPDEMO HL -x -e100 -p -i -oHELPDEMO.TPH HELPDEMO.HL To compile for QuickHelp : HELPC /QH+ HELPDEMO HELPMAKE -e15 -oHELPDEMO.QH HELPDEMO.SRC To compile for TVHC : HELPC /TV+ HELPDEMO TVHC HELPDEMO.TXT To compile for POPHELP : HELPC /PH+ HELPDEMO MAKEHELP /Q HELPDEMO To compile for DESQview/X : HELPC /XD+ HELPDEMO MDVXHELP HELPDEMO.HLP @HELPDEMO.LST COPY HELPDEMO.HLP d:\DVX\HELP To compile for Native Mem Format : HELPC /MT+ HELPDEMO (Use HE HELPDEMO to view that database). To compile for IPF (OS/2) format : HELPC /OS2 HELPDEMO Switch to an OS/2 session. IPFC /INF HELPDEMO (Use the VIEW Command to browse the database). To create a text document with table of contents, glossary and index : HELPC /TXT HELPDEMO To create a word processor document with table of contents, glossary and index : HELPC /RTF HELPDEMO import helpdemo.rtf to your word-processor, and update fields. (e.g. Microsoft WinWord : File|Open to open the document Answer Yes to convert from Rich Text Format Press F9 to update embedded format fields somewhere in the first page (after the Table Of Contents title), and in the last page (after the index title).) ******************************************************************************* * Operation * ******************************************************************************* To start the help engine program enter HELPENG on the command line, and choose the help database you want to view from the list box. Use the Tab key to cycle between hot-link words, and press Enter to go to that link. If you know the name of the SET file of the database you want to activate, you can enter it on the command line, and the help engine will display it. If you have a mouse, you can use it to point at the hi-lighted links, and activate them by pressing the left mouse button. Press the ALT-T key combination to choose from a list of TOPICS in the database, Press ALT-B to go back to the previous displayed TOPIC, Press ALT-X to exit the help engine. The exit command can be given by pressing the right mouse button. Use F10 to open the menu bar, and use the arrow keys to navigate the options. When you find the option you are interested in, Use the Enter key to execute it, or the Esc key to cancel. The menu bar can be navigated using the mouse as well. To create a new help database please refer to the helpC documentation file. If you want to use the Native Mem Format Databases, Please use the supplied HE.EXE program. ******************************************************************************* * Warranty * ******************************************************************************* There is no warranty what so ever, The package is supplied as is, The distributor (ISoft D&M), or the author (Loewy Ron), are not, and will not be responsible for any damages, lost profits, or inconveniences caused by the use, or inability to use this package.

E-Mail : Compuserve - 100274,162 ******************************************************************************* * Trouble Shooting * ******************************************************************************* If you receive some kind of an error message while using the help development kit please refer to this section. tableOps: xxxx error message : This message is generated by the Paradox Engine if an internal error occurs, if you receive a message that is not understood (e.g. Table is busy), please try one of the following : 1. Try running the Help Compiler or the Help Engine with another input and notice if the problem exists, if it does, turn to the next entry, otherwise try to see what the difference between the inputs is. 2. Check your free memory, try to move some TSR's from memory, or use the protected mode compiler/engine available with the registered version. 3. Check if you have loaded DOS SHARE program, it is advised to use SHARE with programs that use the Paradox Engine. If you receive a table busy error, try to see if you have another program that uses the same table in another session (Windows/DESQview etc..). 4. PANIC - Please contact the distributor/author for additional help. Microsoft's HC31 help compiler will generate a error in RTF file error : 1. Re-compile using helpC 4.0+. This should solve the problem, if the problem still exists - please try steps 2 and 3, and notify the author. 2. Use a binary disk editor to look at the character at the position x - 1 in the RTF file (where x is the error position reported by HC31). 3. Try to replace that character from a special PC OEM character to a "standard" ASCII character (such as *). If the problem still occurs, please contact ISoft D&M/The author, otherwise - you probably came across a character that HC31 can not handle. In that case - try using HC300b (the one that generates winHelp 3.0 format), or delete these characters from your source HDF file. Borland's HL help linker will generate a FE02: Out Of Memory error : 1. Re-compile using helpC V3.0+, to include ;INDEX directives after the screen's definitions. Borland's HL help linker will complain about undefined context numbers : 1. You probably have a contents.h file in the current directory, that HL tries to use to bind the help topics to Borland's IDE on-line help, try renaming this file, and re-compile with HL. HelpC will not create the database when compiling to Native Mem (/MT+) : 1. Try compiling with report generation on (/R+) to Native Paradox (/PX+) format. If there are errors, consult the HELPC.LST file, fix them, and re-try. 2. If the database is BIG, you might not have enough memory - Remember that Native Mem tables are generated in memory. You will have to use the HelpCX protected mode compiler (Available with the registered version). HelpEng/HE will complain on an old-database when trying to open a help database with it : 1. Re-Compile the database using helpC. HelpEng/HE will complain on un-supported database format, when trying to open a database : 1. HelpEng can not display Native Mem databases, and HE can not display Native PX databases. Use the other help engine supplied. HE will not be able to open a Native Mem database : 1. Use the protected mode HEX help engine. (Available for registered users). Where is HL - Borland's Help Linker : 1. HL is not included with Borland C++ or Borland Pascal, Borland sells an additional package called Borland Open Architecture (and Borland OA for Pascal) that include among other things - the THELP help linker. We have encountered some users that ran into problems, because they did not use the DOS SHARE program. We advise that you will always load the SHARE program in your AUTOEXEC.BAT file. ******************************************************************************* * Related Products * ******************************************************************************* The following products/packages provide additional HLPDK functionality : 1.

Author : Slren Pingel Dalsgaard (pingel@daimi.aau.dk) ******************************************************************************* * History * ******************************************************************************* Version 1.0 - First Version, Written for TXS V3.0 help system, as part of the WTGEN project, and generalized. Version 1.1 - The Help Engine ALT-X (EXIT) command restores the screen upon termination. - Added /R switch for the helpC help compiler. - From this version the helpC compiler can generate source files for the Microsoft help compiler (HC) from the SAME source .HDF). If the /w+ switch is specified, the helpC compiler will create a .HPJ and .RTF files to create the Windows .HLP file. - Includes a compiled version of the help demo database for Windows winHelp program. (View this if you do not have the Microsoft HC Windows Help Compiler, to see the output that can be generated with the helpC compiler, as a source to the HC compiler). Version 1.2 - Windows RTF files will now display special characters ({, }, \), by prefixing them with the RTF over-ride character (\), when the /W+ switch is given to the helpC compiler. - helpC and helpEng were converted from TP6 to BP7. - The help engine and help compiler use the Paradox Engine V3.0 from this release. (No need to keep your old PXENGINE.OVL file anymore). - Added the /W30 and /W31 switches to the helpC compiler. Use these switches to set the output for the HC30 and HC31 Microsoft Windows help compilers. - The help window scroll bars are shown after a link is executed. (A bug fix). - Added "Trouble Shooting" section to this document. - helpC and helpEng have DPMI versions to handle large projects. (Available only with the registered version). Version 2.0 - The help engine will display a new topic from the first line, and not from the place that shows the current active link. - The help window in the help engine program can now be scrolled to regions of the help topic, that do not include the current, or any link. - A mouse click on a link, when the left-column is not 1 is recognized as it should be. - The helpC help compiler will recognize .TOPIC and .END-TOPIC as topic declaration keywords, as well as the .ENTRY and .END-ENTRY that were used until this version. - The help topic table has a new field in it - the title field, using this field you can specify the title of the help window, when it displays a topic. Because of this field, databases created with older versions of the help development kit will have to be re-compiled. (Please refer to HELPC.DOC). - The helpC help compiler will accept .TITLE keyword after the .ENTRY (.TOPIC) line, to define a title to a topic window. - Added support for Microsoft Quick Help sources, and Borland THELP sources generation. - The helpC compiler will translate ~~ in the source help definition into a ~ sign in the help database. (In versions 1.x you could not include the ~ sign in your help output text). - The help engine will except ALT-B as the go-back short-cut - to display the previous help screen. Version 2.1 - I received several complaints that the HC31.EXE winHelp help compiler does not work, and aborts at a specific place (byte 0x122) on the RTF file created by running HELPC /W31 HLPDK. It seems that for some reason the HC31 compiler is not able to process all of the ASCII characters. The ╔ character that appeared in byte offset 0x121 caused the HC31 compiler to abort. I do not know why this is a problem, I will try to investigate, and if I can not come with an answer - I will try to contact Microsoft (hey folks - they wrote it) and find out. In the mean while - the HLPDK.HDF file provided with this package - can be compiled by the HC31 compiler. - I have noticed that not all of the .HL files generated for THELP users work. I must admit I can not find the reason, I will continue to investigate. I must admit it looks like a problem with the HL documentation I have. In the mean while - please continue to investigate the help development kit, and inform me of any other problems you face with it. - You can contact me (NEW NEW NEW) on my NEW (did I say that ..) Compuserve Address : 100274,162 from Internet that is : 100274.162@compuserve.com . Please send any enhancement requests, bug reports or other things - I'm currently in the process of planning the next major version, and any input will be helpful. - QH (quickHelp) files will now display backslash characters that appear in the source file, by pre-fixing them with the over-ride character (\), when the /QH+ switch is given to the helpC compiler. - QH (quickHelp) links will now be visible, even when they are not hi-lighted. These links will appear in BOLD face, by using the \b bold source command. - For people interested in the HC help compiler - If you do not have it in your development package (I was told that visual basic standard edition does not include it), you can download the 3.0b version from CICA, in the WinWord directory. - NEW - Added TVHC Support - Use the /TV+ switch to create TVHC sources, that you can compile using your version of TVHC (PASCAL or C++). Version 3.0 - The THELP code generation was improved to support HL v6.10 that comes as part of the Borland Pascal Open Architecture package. Because of this change the following things should be noted : 1. The source screens include a ;INDEX directive, so HL will not abort on FE02: Out Of Memory errors. 2. A new dummy screen that is needed for Borland Pascal IDE is generated as the first screen in the source .HL code. You MUST compile the generate code using HL's -e switch, specifying a number which is bigger then 1. HL will always issue one error message - that screen DUMMY is not referenced, this error should be ignored, the resulting .TPH/.TCH file will be a valid THELP and IDE help file. 3. HL V6.0 should still work, with better results, because the Out Of Memory errors should be eliminated as well. (Do remember to use the -e switch with a value > 1). - The .TITLE directive cause titles to be generated for THELP source now. - Added the .LINKCOLOR and .LINKHIGH commands in the Help Definition File (.HDF) - that set the color of links in "normal" and hi-lighted states. This feature is relevant only when compiling to native paradox engine (Help Engine) format. - Added the .INCLUDE commands to the .HDF specifications. Use this help definition file command to create complex help projects that are composed from multiple .HDF source files. - The helpC program will abort with an error message if no .end-topic command was supplied to the last topic in a .HDF file. - Added the ALT-T Topic Index command to the Help Engine. Use ALT-T to display and choose from a list of all the topics in the help database. For ease of use the topics are displayed with their titles. - Upon user's request - The ALT-X command will not have to be confirmed by a TAB in order to exit the Help Engine. - Added support for the Search facility of WinHelp V3.x. From now on the search button of windows help engine will display the list of topic titles available in the help database. - Added the .FIXEDFONT command to the HDF syntax - use this command to set the font used in the generated RTF file for WinHelp V3.x to a fixed font. (By default a proportional font is used). If you find that your help databases are not aligned after they are converted to winHelp format, use this command and re-compile. This command has no effect on targets that are different from windows winHelp formats. - The helpC compiler was converted to perform multiple passes on the input data, if these passes are needed. - The maximum topic name length was expanded to 40 characters - this means that V2.x help databases will have to be re-compiled for this version. - Maximum Text displayed for a link was expanded to 60 characters. - The ALT-B HelpEng command has been enhanced to return to the position viewed last. - Added POPHELP Source Generation. Use the helpC /PH+ parameter to create source that can be used by TurboPower Software's makehelp program - to create a PopHelp .HLP file. - When generating code to winHelp source format, the helpC compiler will issue a warning when an illegal HC link (topic) name is found, and will automatically convert this identifier to a name that is supported by the HC compilers. Version 4.0 - Help Source Generation is much faster in this version, when the target is NOT the native format, and no Report is generated. In this case, helpC storage requirements will be much smaller as well, because no paradox topic and link tables will be created during the compile phase. Please notice that if POPHELP is the target, a temporary paradox table will still be created, during pass 1 pre-processing, pass 2 however, will be much faster than what it was before. Compiling the HLPDK source on my 33MH 486 computer using HELPC HLPDK /w30 /r- takes 1.76 sec. in V3.1 Vs. 5.23 sec. in V3.0. - Added the .PARAGRAPH .. .-END-PARAGRAPH paragraph markers in the topic text section of the .HDF language. Use this feature to create long paragraphs that will be wrapped as one paragraph when the help window is resized by the user. This feature is currently supported for winHelp code generation only. Please refer to the HELPC.DOC file for further discussion of this text formatting feature. - Updated To Paradox Engine 3.01. - For easier development the .TOP and .ENDTOP commands are equivalent to the .TOPIC and .END-TOPIC commands. - If no data file name is given to the helpC compiler, the set name with target specific extension is given instead of the default name given in previous versions. - If the help topics and link names are not specified, names that are derived from the set name are given in this version, instead of the default names that were given in previous versions. - Added support for long topic names, that include spaces in them. Please refer to the HELPC.DOC file, regarding the /ST switch. - Added DESQview/X code generation support. Please refer to the HELPC.DOC File for the /XD+ HELPC Switch. In order to compile the generated source you will have to use MDVXHELP, by Daniel J. Bodoh, that can be found in the file DVXHLP10.ZIP in the DV-X directory on SIMTEL20, and probably some other places on the Internet, and other networks. - When generating code to THELP source format, the helpC compiler will issue a warning when an illegal HL link (topic) name is found, and will automatically convert this identifier to a name that is supported by the HL compiler. - Added the .PCFONT command to the HDF syntax - use this command to set the font used in the generated RTF file for winHelp V3.x to a terminal font. (By default a proportional font is used). If you convert your help database that uses PC special characters, and you want to preserve these characters in the windows version, use this statement. This command has no effect on targets that are different from windows winHelp formats. - When compiling to winHelp format, character with ordinal number bigger than 127 will be translated using the RTF override mechanism. The "Famous" HC31 problem is over.. . (This solution was offered by Mr. Lars Fosdal.) - When generating to winHelp Target, TAB characters are translated to RTF \TAB commands. For other targets no TAB translation is performed. It is advised that you set your editor to fill spaces when a tab is inserted. - Added the /CS switch to the helpC compiler. Using this switch topics and links can be set to be case sensitive. It is not advised to use this switch, unless you want to create lower case indexes in a help engine such as POPHELP or THELP. Please notice - setting this switch to ON (+) can break help databases that used to compile fine. Use With Care!. (By default case sensitivity is set to off). - The HELPENG help engine can now handle topics with up to 500 lines, vs. 125 in the previous version. Version 5.0 - The helpC compiler will convert illegal winHelp 3.1 (HC31) characters in titles to spaces. The previous version corrected only body text, but did not detect illegal titles. - When THELP (HL) is the target, The OVERVIEW topic will be renamed to Index - This is the name that MUST be attached to ;MainIndex screens in THELP, if we want the IDE to display them as the main index. - The helpC compiler will look for a configuration file called HELPC.CFG in the current directory, and if it finds one will process the switches in this file before any other command line switches. - Control Characters (ASCII < 32) are not acceptable by HC31 as well, helpC will now create the RTF over-ride for these characters as well. - Reports use virtual memory tables for cross reference manipulation, so compile with report generation is faster. On my 486-33 computer compiling HELPC HLPDK /W31 /R+ took 11 sec. in the previous version Vs. 5 sec. only in this version. As a side effect - the compiler will not create the helpct* temporary tables. - During Pass 1 of POPHELP and DV/X source generation - a temporary memory table will be used instead of a paradox table in previous versions. Code generation will be both faster, and will not require disk space for these targets. On my computer HELPC /R- /PH+ HLPDK takes 2.32 sec. Vs. 3.24 sec. on the previous version. - Added the .TEXTCOLOR command to the HDF syntax. Use this command to set the value of the text color. This command is supported only in the Native help format target. - Added The menu-bar to the helpEng help engine program. - The helpEng program can display multiple help windows. - Added the ability to save and print a help topic from within the help engine. - Fixed a bug in the cross reference report that was cutting long link names, and report on errors that did not exist. - A NEW Optimized Native help database format is introduced with this version. The new Native Mem format uses Fast, Optimized code with memory based indexes to display help faster, and with less distribution overhead. The HE.EXE Help Engine supplied with this version is smaller in size than HELPENG.EXE, because it does not have the Paradox Engine in it. The Help Databases Generated are smaller, because the format is simple RAW Binary representation of the data structures handled in memory by the help engine. - The helpC compiler now supports the /MT+ switch to generate the new Native Mem Format. - The Help Engine Source Code is now available to registered users, (for additional cost) for the New Native Mem Format. - The Native Paradox Based format is still supported in this version, and should be used to handle Huge help databases that will not fit into memory, or to support PAL/ObjectPAL help applications from within Paradox/Paradox for Windows. Use the helpC /PX+ switch to generate code to this target. The HelpEng.EXE help engine is supplied with this package as well. Version 6.0 - The helpEng and HE help engines will not terminate abnormally when the Print or Save Topic commands are given with an empty desktop, the help engine will issue a warning message and continue instead. - The Help Engines will restore the initial text cursor size upon termination. This was noticed by Prof. Timo Salmi of Vaasa, Finland. - Added the Navigate menu to the help engines. Use this menu's entries to navigate the help database - choose from the overview screen, and index entries. - Added keyword support to help databases using the .KEYWORDS help definition file syntax. Use this command to add multiple indexes, or search by keywords to your help databases. In this version of the helpC compiler, Native (/PX+, /MT+), winHelp (/W30, /W31) and THELP (/TH+) sources support the keywords defined for topics. Please refer to the HELPC.DOC file for a formal discussion of this feature. - The set format file has been changed to support the keyword tables, old databases will have to be re-compiled for use with the help engines. - Added the ALT-S (Search command) to the help windows in the HELPENG program. Use this command to search on the keywords defined in the help database. - Added OS/2 IPF source generation. Use the /os2 switch of the helpC compiler to generate code to the OS/2 IPFC compiler. Paragraph support (.par .. .endpar/.paragraph .. .end-paragraph) is available in this target as well. - The number of input lines displayed as processed by the helpC compiler include the actual number of input lines in the source HDF file, vs. topic text lines only in the previous version. - helpC error reporting has been improved to include the line number the error occurred on. Version 7.0 - The helpC compiler will perform RTF overrides in topic's names from this version. In previous versions if you had a character that had to be overridden in a topic name, hot links could not access it, because hot-links were overridden with a prefix '\' character, while topic names were not. - Added the /WD switch to the helpC compiler. If you do not want to see the information about topics and links that were translated in order to be compatible with the target source, turn Warning Display to Off using /WD- - Added Conditional Defines to the compiler. Use the Conditional define statements (.ifdef/.ifndef/.else/.endif) to compile different parts of your source according to different defines. Please refer to the HELPC.DOC file for a complete discussion of this important feature. - Added the /TXT switch to the helpC compiler. Use this switch to create a text document with page breaks, headers and footers from your input source .HDF file. With this option the helpC compiler allows you to create both on-line help and printed documentation from the same source! - The /TXT format creates a Table Of Contents and Index files as well that you might want to print with your text document. - The Cross Reference Report format was improved to be displayed in 80 columns. Link Error lines have been improved to include the link name for quick error diagnostic. D.J. Murdoch is the man that suggested these enhancements. - The title string in the topics table has been expanded to 70 characters. This was done to allow longer titles in /TXT /PX+ and /MT+ targets. Old Native help databases will have to be re-compiled. - The help engines will be able to display topics of up to 16K lines, vs. 500 only in previous versions. - The topic's title will be seen in winHelp's secondary (Go To) list box of the search function, instead of the topic name that was used in previous versions. Thanks for D.J Murdoch that noticed this bug of mine. - Added .PAGELENGTH and .PAGEWIDTH statements to the .HDF syntax. Use these statements to set the printed page size in /TXT targets. - A bug in winHelp's HCP that does not parse the RTF \tab statement has been over-ridden by helpC that replaces TAB characters with a RTF group that contains the \tab character. Version 8.0 - Added the /RM switch to the helpC compiler. If you set this switch off (/RM-) the cross reference temporary tables will be created on disk instead of in memory. The disadvantage is that the report will be much slower, the advantage - you will need less memory for the compiler. When you try to compile huge databases, and do not have enough memory, use this option. (By default /RM is set to on /RM+). - Native format databases include a new field - tType of 1 character in the topics table. This character is needed to support different types of topics. Databases from previous versions will have to be re-compiled. - Added support for advanced word processors with the helpC /RTF switch. Use this switch to create a version of documentation that can be imported, with smart formatting options, by word processors that support the RTF format. (Such as Microsoft Word for Windows, Word Perfect for Windows and Lotus AMI PRO). With the introduction of this option - you can create help database to multiple platforms, formatted text for "readme" computerized documentation and professional word processor documentation from the same source!. - Added the .POPUP and .END-POPUP (.ENDPOP) commands to the HDF syntax. Use these commands to define popup definition topics. Popup definition topics are used as glossary entries that the user can consult to see a definition without losing the current position in the topic he is reading. POPUP entries are supported in the winHelp, Native Paradox and Native Memory formats. In the other targets, the popup entries are used as regular topics. - In the Text and RTF targets the popup entries will be converted to a glossary file/chapter, You can add this file as an appendix to your document file. - Added a conditional define (NATIVE) when helpC /PX+, /MT+ targets are chosen. Version 9.0 - Added support for automatic group menu generation. Use this feature to associate sets of topics to groups, and create menus of these groups in different places. - To support the groups functions, the .GROUPS and .INSERT GROUP statements were added to the HDF syntax. Please refer to the helpc.doc documentation for discussion of these statements. - Improved character format control. From this version you can specify text attributes on the paragraph start statement, to choose the font, size etc. .. of the paragraph text. This support is currently available to winHelp and RTF targets, in the other targets, these attributes are ignored. Please refer to helpC documentation for further discussion of this feature. - Added the .SETFONT command to the HDF syntax. Use this command to change or add new fonts to the font palette. - Added the .TITLEATTR topic attribute to the .HDF syntax, use this statement to define text attributes to the topic title. Please refer to the helpC documentation about this feature. - Added the .TITLEDEFAULTS statement to the .HDF syntax. Use this command to set default attributes to all the topic titles. These defaults can be over-ridden with the .TITLEATTR statement described above. - Added the .INSERT CODE and .END-CODE statements, use these statements to insert target code in your .HDF sources. Code inserted between these 2 statements is sent to the output file with no translation by helpC. - Replaced the helpC /D, /L, /H and /K switches with /ND:, /NL:, /NT: and /NK: - The new switches were needed because of the number of options that should be specified on the command line, as well as the fact that they are easier to remember now. - Added the ability to define a conditional define on the command line of the helpC compiler, using the /D: switch. - Added the .ATTRDEDAULTS statement to the .HDF syntax. Use this statement to set the default paragraph attributes. Please refer to the helpc.doc file for documentation on this function. - If no default font or attribute is set in the winHelp and RTF targets Times New Roman is the default font vs. Tms Rmn in previous version. - Added the .EXT-TOPIC topic definition statement. This statement defines a topic (like the other topics defined with .TOPIC/.ENTRY etc..), and also creates an external reference to that topic to be called from an external program. - Added the /ED= switch to the helpC command line. /ED=P (Default) creates the external definitions (if any) in a PASCAL unit format, /ED=C creates the external definitions in a C/C++ header file. - Added the DOCUMENT conditional define if /RTF or /TXT attributes are set. This way you can easily set document text for both targets. - In POPHELP (/PH+) target, the !INDEX directive is added, so topics are ordered in the main index file in the order they appear in the source HDF file. ******************************************************************************* * Credits * ******************************************************************************* HELPENG, HELPC were written using Turbo Pascal 6.0, and Borland Pascal 7.0, Paradox Engine 2.0, and Paradox Engine 3.0, 3.01.
