When INTERHLP is first run, it builds a map of the interrupt data file. It uses this map to display an index of entries and to find the selected entry for display. installation: Copy all of the distribution files into a convenient directory. They must all reside in the same directory so that they can be found by INTERHLP. INTERRUPT.LST must also reside in this directory unless specified as part of the command tail. The Interrupt List is distributed in many pieces (named INTERRUP.?). These files must be combined together by running COMBINE.BAT (supplied with most releases of the Interrupt List) or by appending them to each other using COPY. COPY INTERRUP.A + INTERRUP.B + INTERRUP.C INTERRUP.LST COPY INTERRUP.LST + INTERRUP.D + INTERRUP.E INTERRUP.LST etc. usage: INTERHLP [-cX] [filename] [interrupt] ["string"] where: -Cx Selects Category 'x' Note that category specifiers are case sensitive! filename Optional list file. The default file name is INTERRUP.LST and the default path is the location of INTERHLP.EXE. interrupt Optional topic code in the form: INTERRUPT nn FUNCTION nn SUBFUNCTION nn All field are optional and the field specifiers can be omitted if the arguments are presented in the above order. "string" Optional title sub-string. The first time INTERHLP is run (and anytime it detects a new data file), it reads the entire data file (this takes a few minutes!) and builds a map of its contents. It then searches for the specified topic and displays it if found. If the topic isn't found, or no topic is specified, an index of the entries is displayed. Each line of the index display consists of a topic ID and the text of the first line of the entry. The topic ID consists of a letter which designates the category and a number which designates the interrupt and function. To select a topic, use the cursor keys to move the hilite bar to the desired selection and press the enter key or point to the selection with the mouse and click the left button. Topics can also be selected using the search function. This function prompts the operator for a search pattern which is in the form: INTERRUPT nn FUNCTION nn SUBFUNCTION nn "title_text" All fields are optional and the field designators can be omitted if the arguments are presented in this order. Field designators can be abbreviated. Searches for numeric int/func/subfunc are fast binary searches of the index map. Text searches are linear searches of the first line of each entry which satisfies the numeric search criteria and are much slower. While a topic is being displayed, the cursor keys move up and down within the current topic and to the adjacent topics. As topics are selected, they are recorded in a history queue. The operator can walk back and forth thru the history queue by pressing F7 and F8. Searches within the topic display are simple text searches. Many entries in the Interrupt List have cross-references to other entries in the form of lines starting with "SeeAlso:". If the mouse pointer is positioned on one of these lines, and the left button is clicked, INTERHLP will try to find the referenced entry and display it. Note that if a category other then "all" is chosen, some references may not be found. The entries in the Interrupt List are grouped by category. The first character of each topic code is a letter which designates a category. By default, INTERHLP displays all categories. When appropriate, a category can be selected from the CATEGORY menu and only the entries in that category will be displayed. ======================================================================== Please forward all comments and bug reports to: Gary Chanson 31 Chester Avenue Waltham, MA 02154 Voice: 617-899-4771 Email: Gary.Chanson@Channel1.com 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � � � For on-line support, call our BBS! � � � � Arcane Incantations � � 617-899-6672 � � � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸
