Scroll 1.00 =========== Scroll is a scrolling textfile reader. You can scroll upwards and downwards through text files of any length. Extended View highlight codes as used by *lp and *lpS are acted on to give bold, italics, superscript, wide, subscript and underline effects. These can be turned off to give plain View extensions of *bold* and underline. If there is enough memory, Scroll uses shadow mode 0, otherwise mode 3 is used. Unless a command line file is given, Scroll shows the current directory and asks for a filename. At this prompt you can also give *commands to change directory, etc. Once a file is given, it is loaded and displayed. The keys are simple. Cursors move up and down. Pressing Shift will jump one screen at a time. Pressing Ctrl will jump to the ends of the file. Pressing COPY will flip between extended highlights and plain highlights. Pressing Escape will leave. Pressing P and RETURN will let you print out the file. Before you press RETURN a prompt appears telling you the name of the printout command. You can change this here by deleting it and typing in another comand, but Scroll will usually have found a suitable one. The recommended command *lp comand is created with the MakeLP program. The bottom line of the screen shows the filename of the file being scrolled, a percentage figure showing how far through the file you are, and a reminder of the keys used. Scroll will take command line arguments when run as a *command or passed via the keyboard buffer. The parameters are: *Scroll <afsp> (-quit (*)<name>) The <afsp> is the file to display. The -quit option gives a file to run on exit. If the name starts with a *, then it is called as a *Command, otherwise it is CHAINed. The -quit option must be in lower case, and only the first letter is significant. So, for instance, to call Scroll from another program, you could use the following: OSCLI "KEY0 |@"+name$+" -quit Menu" *FX138,0,192 CHAIN "Scroll" This would run Scroll and display the file name$, and on exit would return to the program Menu. On starting, Scroll looks for a *lp printout program. The order it looks for one is: lp, %.lp, %.lp.#, %.lp.*, $.lp, :0.$.lp. The recommended place to put the *lp command is in the library in a subdirectory %.lp, with a file 1 being a default general purpose printer. With DFS, the best place would be in the $ directory. Scroll consists of the following files: Scroll - The program disp - Controls screen output giving display effects T/Scroll - This text file. NB: The current version will only display files which have each line terminated with CR.
