The LIST statement uses the following configuration ,
LIST "D# : filename"[ , beginline] [endline]*
where 0 specifies the device name. # is an optional parameter
which specifies the drive number. The filename assigned to the
file
is specified in filename.
beginline and endline are optional parameters which specify the
first and last
line numbers to be stored by LIST. Ailline numbers
with values between beginline and endline will be stored as well.
For example, the following LIST statement would save all
program lines
between 100 and 500 inclusive on the diskette in
drive 2 with the filename PROGA.BAS:
LIST "D2:PROGA.BAS", 100, 500
The LIST statement saves programs in Atari ASCII format. In this
format, every character is assigned an ASCII code.
Loading a Program
The LOAD statement is used to load programs into memory from
diskette which were previously saved in tokenized format by the
SAVE statement.
The
LOAD statement uses the same format as the SAVE
statement. The following LOAD statement would load
PROGA.BAS from drive 1:
LOAD "D:PROGA .BAS"
The ENTER statement is used to load a program previously saved
in
ASCII format with a LIST statement. The following ENTER
statement would load PROGB.BAS from drive 1:
ENTER "D:PROGB.BAS"
