This will read the directory off a disk and display it on the screen. The display will halt when a full page has been displayed. To halt the listing before the end of the page has been reached, press the RUN/STOP or NO SCROLL key. If you prefer the directory to scroll continuously, hold down the LINE FEED key. To halt the listing, release the LINE FEED key. You can continue by pressing the space bar, or exit by pressing the ESC key. Pressing the HOME key at any point will re-display the directory. When the directory is halted, a flashing pointer will appear. Using the cursor keys you can move the pointer up and down to select a file. Using the 80 column screen will give you the advantage of being able to see the various command keys. You have the following options:
RETURN:
Will load the file into memory and run it as a BASIC program, similar to RUN "filename"
F1:
Will do the equivalent of DLOAD "filename"
F3:
Will do the equivalent of BLOAD "filename",b0 (will use bank 0). Unlike the others, this command will return to THE SERVANT's main menu after the file has been loaded.
F5:
Will do the equivalent of BOOT "filename", using bank 0 while loading. Please note however, if the start address of the program is lower than 16384 ($4000) the computer will be configured to bank 15 when the program is executed. PLEASE NOTE: Using BOOT "filename" in BASIC will in some cases get you into trouble. It won't work with RAMDOS, and some older 128's may malfunction when using a slow serial disk drive (1541 for example). You won't encounter these problems with THE SERVANT.
F7:
Will load the program, switch to 64 mode, and run it. 1571 disk drives will NOT be switched to 1541 mode. You can load programs of up to 249 blocks in size.
S:
Will scratch the selected file, but you will be asked to confirm before the action is performed.
T:
Will "type" the file as ASCII, meaning that it will display the file contents, whatever it is, on the screen. Control codes will be displayed as their reversed counterparts; no file will "upset" the screen. SEQ, PRG, USR, REL and even DEL files can be displayed with equal ease. Unfortunately, most GEOS files has a structure which can't be displayed. Please note that you won't be limited to text files. You may equally well list a program, allowing you to read text which is embedded in the code. This may sometimes reveal things about the program which would otherwise be difficult to disclose. Press space to halt, space again to continue, HOME to re-type the file from the beginning, ESC to exit.
SHIFT/T:
Will display the file as SCREEN CODES. Normal and reversed characters will be displayed as such. This feature is especially advantageous with word processor files which is often stored in screencode format. Such word processors normally use the backarrow to serve as carriage return. The screencode lister will therefore begin a new line whenever a backarrow code is encountered.
If you find that you should have selected another "type" mode, simply press T again along with the appropriate shift key (if any) and the file will be re-displayed using that mode.
RETURN:
Can also be used to select 1581 subdirectories. When the cursor points at a "CBM" file, the RETURN key will select that subdirectory.
/:
Will select the root directory if you're using a 1581 drive.
