LOAD "T" will find the first program on the tape beginning with the letter T.

And LOAD "HELLO" will find the first program beginning with the letters

HELLO, like "HELLO THERE."

When using the disk, this option is called pattern matching, and there is a

special character in the file name used to designate this. The asterisk (*)

character following any program name tells the drive you want to find any

program starting with that name.

LOAD name$ + "*", 8

Can Be A String

Variable Or The

Name Inside Quotes

FORMAT FOR PATTERN MATCHING:

In other words, if you want to LOAD the first program on the disk

starting with the letter T, use the command LOAD "T*", 8.

If only the "* is used for the name, the last program accessed on the disk

is the one LOADed. If no program has yet been LOADed, the first one listed in

the directory is the one used.

You are probably familiar with the concept of wild cards in poker where

one card can replace any other card needed. ,On your 1541, the question mark

(?) can be. used as a wild .card on the disk. The program name on the disk is

compared to the name in the LOAD command, but any characters where there is

a questionmarkin the namearen't checked. '

For instance, when the command LOAD "T?NT", 8 is given, programs

that match include TINT, TENT, etc.

When LOADing the directory of the disk, pattern matching and wild cards

can be used to check for a list of specific programs. If you gave the command

LOAD "$O:TEST", only the program TEST would appear in the directory (if

present on the disk). The command LOAD "$O:t*" would giveyou a directory

of aU programs beginning with the letter T. And LOAD "$O:T?ST" would give

you all the programs with 4-letter names having the first letter of T and the third

and fourth letters ST. LOAD "$O:T?ST*" would give names of any length with

the correct first, third, and fourth letters.

SAVE

To SAVE a program to the diskette, all that is needed is to add the device

number after the program name. Just like the SAVE command for the tape

deck, the device number can be folJowed by a command number, to prevent the

automatic re-Iocation on LOADing (see the section on the LOAD 'command,

above).

FORMAT FOR THE SAVE COMMAND:
