- it scrolls alternately 1 and 2 pels). The following commands may be typed

- >>>> REQUIRES IBM ENHANCED GRAPHICS ADAPTOR <<<<
-
- Purpose:
- Smooth scrolling type file to screen.
-
- Usage:
-
- STYPE FILENAME
- or
- STYPE (uses standard in)
-
-
- Description:
- STYPE types a file to the screen controlled by an IBM Enhanced Graphics
- Adaptor, using variable speed smooth scroll. If no file name is supplied, it
- will read from standard in (eg: STYPE < FILENAME, or PROGRAM | STYPE), and
- thus can act as a "MORE" type filter. The EGA must be in 25 line character
- mode. The EGA must be the current console device; this requirement is new with
- this version. It can be emulating either the IBM Monochrome Display and Printer
- Adaptor or the IBM Color/Graphics Monitor Adaptor, or it can be in the new
- Enhanced Color Mode (25 lines, character rows 14 pels high).
-
- The scroll speed may vary from stopped (0) to one line per vertical
- retrace (speed 14 in mono mode, or 8 in color mode), by units of 1/2. The
- speed represents the number of vertical pels scrolled per vertical retrace.
- (A speed of 1/2 means it scrolls 1 pel every 2 retraces, or speed 1 1/2 means
- it scrolls alternately 1 and 2 pels). The following commands may be typed
- while stype is showing the file:
-
- + increment speed by 1/2 unit (up to max speed)
- - decrement speed by 1/2 unit (down to zero, or stopped)
- 0-9 set speed to number given
- space pause if moving, restart if paused [new action this version]
-
- Any other key will abort stype and return to DOS.
-
-
- Problems:
- It will not support graphic modes, nor the new 43 line character modes
- currently. 43 line mode is some trouble and may require temporarily blanking
- or glitching the screen on exit.
- It cannot detect what mode the EGA is in unless it is the current
- CON: device, thus the requirement that the EGA be the current console. Use
- version 1.1 if you want the EGA to scroll whether or not it is the console -
- but the EGA must then be either standard mono or standard color, not in any
- new mode.
