READ            READ variable [, variable]                              490 READ V,W

                Read data into specified variables from a

                DATA statement.  The first piece of data

                read will be the first piece of data listed in

                the first DATA statement of the program.

                The second piece of data read will be the

                second piece listed in the first DATA

                statement, and so on.  When all of the data

                have been read from the first DATA state-

                ment, the next piece of data to be read will

                be the first piece listed in the second DATA

                statement of the program.  Attempting to

                read more data than there is in all the

                DATA statements in a program will cause

                an OD (out of data) error.

SPC             SPC (expression)                                        250 PRINT SPC(I)

                Prints I space [or blank) characters on the

                terminal.  May be used only in a PRINT

                statement.  I must be =>0 and <=255 or

                an FC error will result.

STATEMENT       SYNTAX/FUNCTION                                         EXAMPLE

TAB             TAB (expression)                                        240 PRINT TAB(I)

                Spaces to the specified print position

                (column) on the printer.  May be used

                only in PRINT statements.  Zero is the

                leftmost column on the termainl, 19 the

                rightmost.  If the carriage is beyond pos

                position I, then no printing is done.  I must

                be =>0 and <=255.

                If I is greater than 19, the printer will skip

                the required number of lines to arrive at

                the specified position.

ASC             ASC (string expression)                                 300 PRINT ASC(X$)

                Returns the ASCII numeric value of the

                first character of the string expression X$.

                See Appendix E for an ASCII/number

                conversion table.  An FC error will occur

                if X$ is the null string.

STATEMENT       SYNTAX/FUNCTION                                         EXAMPLE

CHR$            CHR$ (expression)                                       275 PRINT CHR$(I)

                Returns one character, the ASCII equiva-

                lent of the argument (I) which must be a

                number between 0 and 255.  See Appendix E.
