specified. This is relevant only when the program has a

name, that is, if it was retrieved by the GET command or

named with the NAME command. If you have just typed in

the program, and have not used the NAME command, the

program will not have a name.

FORMATTED The listing is formatted using a set of the compiler

FORMAT listing options that appear in the program if this

parameter is specified. The set of COPTIONS used to

format the interpreter listing are: LINES, LIST, ID

TABLES, PAGE, PAGESUB, TITLE, and TITLESUB. These are

explained in chapter 9.

The LIST command may add or remove blanks and parentheses to make lines

more readable. It also does the following:

* Lists lines in line number order, whether or not they were entered in

that order.

* Lists identifiers with first letters upshifted and all other letters

downshifted.

* Lists keywords in all uppercase letters.

* Lists empty statements as empty comments (for example, it lists the

line "500 Label:" as "500 Label: !").

The column at which long lines are broken depends on the output device

and WIDTH. On a terminal screen, the default line length is 80; on a line

printer, it is 132.

If a line exceeds the maximum length, the LIST command prints an asterisk

(*) in its last column and truncates the line at the maximum length.

To stop the LIST command, press CONTROL Y.

Examples

The following example shows the LIST command. Without parameters, the

LIST command below displays the entire program. When LIST has the

parameter 10/90, lines 10 through 90 are displayed.
