- TYPE.PRG
-
- The TYPE.PRG is used to read the User's Manual on disk, SEURAT.DOC.
- Think of it as a tutorial driver program.
-
- TYPE is intended to replace the "Show" option that appears when you
- double-click on a non-executable file from the Desktop.
-
- TYPE scrolls forward and backward by page or by line and allows you
- to jump to the end or beginning of a document. It prints to the screen at
- a rate an order of magnitude faster than the "Show" option.
-
- TYPE does not buffer input but loads the entire file into memory and
- formats the text before displaying it (at 7565 bytes per second). For a
- smallish file, the "Show" option is probably faster to use, but for any
- textfile larger than 6kb to 8kb, TYPE pulls ahead!
-
- Since TYPE.PRG looks at the basepage, you can install your .DOC or
- .LST or .MSS files as an application for the TYPE.PRG. Then, when you
- double-click on a document, the TYPE.PRG will take over and show it,
- instead of TOS.
-
- It is particularly useful when operating in low resolution, since it
- generates an full 80-column display, regardless of the resolution at the
- Desktop level.
-
- It has some limitations. The length of file it will accept is
- limited by available memory and is determined by the program. If the file
- you wish to read is too long, an alert will notify you of the maximum file
- size that the program can handle before aborting the read.
-
- TYPE is configured to deal with a maximum of 2200 lines of text. If
- it loads a text file of less than the maximum size that has more than 2200
- lines, it will truncate the file and display the first 2200 lines of text.
-
- If the file TYPE loads has no carriage return in the first 256 bytes,
- TYPE will abort the read, as a safeguard against trying to display program
- and data files, but the user will be alerted as to the cause.
-
- TYPE checks the first line of the file to see if that text line is
- longer than 240 characters and aborts (again, with alert) if it is. If
- lines longer than 80 characters occur in the file, they will be doubled
- over (up to 240 characters).
-
- The specific commands for TYPE.PRG are as follows:
- The up arrow cursor key scrolls the document backward one page.
- The down arrow cursor key scrolls the document forward one page.
- The left arrow cursor key scrolls the document backward one line.
- The right arrow cursor key scrolls the document forward one line.
-
- Any number key on the keyboard ('1' through '9') scrolls the document
- in the last previously called direction and with an increment that is
- multiplied by the number keyed. That is, if you have just scrolled
- backward by one line and you press the 9 key next, TYPE will scroll
- backward by nine lines. If you had just paged forward, pressing the '9'
- key would jump you ahead by nine pages.
-
- The <Clr/Home> key jumps to the beginning of the document.
- The <Insert> key jumps to the last page of the document.
- The <Undo> key Quits the read and returns you to GEM Desktop.
-
- 24 lines are displayed and a command ledger line appears at the
- bottom of each page.
-
- TYPE pages with an overlap of one line to assure you reading
- continuity. Page boundaries are not fixed, but always begin with the
- currently displayed screen.
