Apple II User Manual

BASIC will reply with:

    10 PRINT 2+3

    20 PRINT 2-3

DELETING A LINE

Sometimes it is desirable to delete a line of a program altogether.  This is accomplished by typing

the Line Number of the line so be deleted, followed by a carriage return.

Type in the following:

    10

    LIST

BASIC will reply with:

    20 PRINT 2-3

We have now deleted line 10 from the program.

REPLACING A LINE

You can replace line 10, rather than just deleting it, by typing the new line 10 and hitting

RETURN.

Type in the following:

    10 PRINT 3-3

    LIST

BASIC will reply with:

    10 PRINT 3-3

    20 PRINT 2-3

It is not recommended that lines be numbered consecutively.  It may become necessary to insert a

new line between two existing lines.  An increment of 10 between line numbers is generally sufficient.

DELETING A PROGRAM

If you want to delete the complete program currently stored in memory, type in "NEW."  If you

are finished running one program and are about to read in a new one, be sure to type in "NEW"

first.

Type in the following:

    NEW

Now type in:

    LIST

204  PRINTING DATA

If is often desirable to include explanatory text along with answers that are printed out.

Type in the following:

    PRINT "ONE HALF EQUALS", 1/2

BASIC will reply with:

    ONE THIRD EOUALS

    .5

As explained in Subject 202, including a "," in a PRINT statement causes it to space over to the

next 10-column field before the value following the "," is printed.
