CURSOR.100 by Fred Edelkamp, edited by Robert Benson
CURSOR.BA creates CURSOR.CO and was made with TCOMP, it's 2832 bytes long and is relocatable.
CURSOR is a machine language program that allows you to view 60 columns by 10 lines on your Model 100. This means 600 characters can be displayed at a time, almost as much as the Tandy 200. CURSOR was written to supplement pixel-mapping, to help find and correct formatting errors. I do not advocate writing a book with it but you can save a lot of paper by using CURSOR to look at text files before printing them.
CURSOR allows you to view your text the way it will be printed while allowing you to edit the file. CURSOR has all uppercase and lowercase characters with descenders, the display is readable and easy to use. Characters below CHR$(32) and above CHR$(125) are displayed as a CHR$(255). CURSOR will word wrap on a dash (-) and characters below.
CURSOR supports insert and delete or you can overtype characters, it starts up in the Insert mode. At any time you can enter the 100's text editor and when done return directly to CURSOR. Cut and Paste are not supported, as the TCOMP's INKEY$ instruction has a problem with them.
Backspace and delete work normally and the arrow keys work almost normally. If you press [Up Arrow] while the cursor is on the top line of a screen, the cursor will move to the top of the file. If you press [Down Arrow] while the cursor is on the bottom line of a screen the cursor will move to the next page, the last line of the current screen is the first line of the next screen.
When you run CURSOR you will see the files in memory and be asked for one, enter a file name (without extension) and press ENTER. The screen will clear and display the first screen of text. At the top left corner there will be a small flashing cursor (hence its name). If you enter a invalid file name CURSOR will return you to the main Menu.
[CTRL-V] Toggles between the Insert and Overwrite modes, the cursor is a little larger when in the Overwrite mode. Whenever a character is input the whole screen is rewritten however the you do not have to wait on the screen, type as fast as you like CURSOR will keep up.
[SHIFT UP] Moves to top of the page.
[SHIFT DOWN] Moves to the last character on the page.
[SHIFT RIGHT] Moves to the character after the next space to the right.
[SHIFT LEFT] Moves to the character before the next space to the left.
[CTRL UP] Moves to the top of the file.
[CTRL DOWN] Moves to the next page.
[CTRL LEFT] Moves to the start of line.
[CTRL RIGHT] Moves to the end of line.
[F8] and [ESC] Return to the main Menu.
[F4] Takes you into the text file you working on. When you exit text you will be returned to CURSOR.
NOTE: Be sure to BACKUP all files in RAM before running any CO program!
