Once you start this option the speed of operation will depend on the size of
files stored in the card. The screen will scroll up when the listing reaches the
bottom of the screen. You can pause the scanning of the card by pressing any
key.
ESC will quit out of the S option altogether.

Q quits SMCRead and returns to DOS.
3. File Name Conventions
For all options where SMCRead asks you for a file name, if you enter a file
name that contains ‘ * ’ or a ‘ ? ’ wildcard character a list of files of that
specification is displayed on the screen. You are then prompted to enter the
file name again.
You can abort an option at this point by not entering any name and pressing
the
ESC key.
If you have already entered a file name, before running an option, SMCRead
prompts you with the same name again. Pressing the
ENTER key at this stage
accepts the previously entered name. To enter a different name, type out the
new name in full and press
ENTER .
SMCRead assumes a .DLD extension for program files and a .DAT extension
for data files, unless you enter an alternative extension or specify no extension
by terminating the file name with a ‘.’
For options where only one file can be read from, or stored in the card, e.g. the
name of a program to be stored in the card, SMCRead asks you for a specific
file name, where the prefix can be up to eight characters long.
Where the option can generate several files on disk, e.g. options A or P,
SMCRead asks for a ‘root’ file name. You should enter a name that has six
characters or less. SMCRead then appends a number to the name, which is
incremented with each file read. Where the file name is six characters long the
numbers 01 to 99 are appended to the name. Shorter names have a three-digit
number appended, i.e. 001..999.
When you first specify the root file name, SMCRead scans the disk for files
with the same root name. If none are found, SMCRead starts numbering the
files at 1, e.g. ROOT001.DAT. If files with the same root name exist, new
files are numbered sequentially starting with the first number that does not
exist on the disk, e.g. if ROOT001.DAT and ROOT002.DAT already exist, the
first new file will be called ROOT003.DAT.
If you specify a file that already exists on disk you are asked if you wish to
overwrite the file. If you reply ‘N’ or ‘No’, the option aborts and returns to the
options menu.
