CHRS(n)
n: numeric value (greater than 32)
Returns the character whose ASCII code is integer expression n.
When a space is to be displayed, use PRINT “‘..”” or PRINT SPC(1).
Examples: A$ = CHR$(65)
Returns ‘‘A’’, which has an ASCII code of 65.
PRINT CHR$(107)
Displays the graphics character ‘‘fQ’’, which has an ASCII code of 107. Multiple
ASCII codes can be specified as follows:
A$ = CHR$(65,66,67,68)
LEN(x$)
x$: character string
Returns the number of characters in string x$.
Example: A=LEN(‘‘ABC’’)
Returns the number 3, which is the number of characters in string ‘‘ABC’’.
(4) Random number functions
RND(n)
n: numeric value
This function returns a pseudo random number for a given numeric value.
* Pseudo random numbers are generated from values between 0.00000001 and 0.99999999.
* When the numeric value specified is greater than 0, the function gives the next pseudo-random number
in the current sequence.
* When the numeric value is less than or equal to 0, RND generates a new pseudo-random number
set whose initial value is determined by the value specified for X, and gives the first number of
the new set. This makes an operation such as a simulation with random numbers repetitive.
Example:
To generate a random number which is an integer from N to M, use the following formula:
INT(RND(X) * (M—N +1) +N)
The following program draws a number of circles. The radius of the circles and the coodinates are
given by the random number.
10 FOR A=1 TO 100
20 B=RND(1)* 320
30 C =RND(1)* 200
40 D=RND(1)* 100
50 E=INT(RND(1)* 4)
60 CIRCLE [E,0]B,C,D
70 NEXT A
80 END
