STRING$
Function
STRING$( number,character)
Returns a string containing the specified number of character.
Number
must be in the range 0 to 255.
Character is a string or an ASCII code. If you use a string con-
stant,
you must enclose it in quotation marks. All the characters
in the string have either the ASCII code, or the
first letter of the
string specified.
STRING$ is useful
for creating graphs or tables.
Examples:
B$ = STRINGSC25, “X”)
puts a string of 25 “X”s into B$.
PRINT STRING$(50, 10)
prints 50 blank lines on the display, because 10 is the ASCII
code
for a line feed.
