COMMANDS AND FUNCTIONS

Single-dimensional array:

ARRAY myArray(5)

FOR i = 1 TO 5

myArray(i) = i * 2 REM Duplicate the number’s value inside the array

NEXT i

REM myArray(i) now contains values 2 4 6 8 10

Multi-dimensional array:

ARRAY myArray$(3,7) REM 2-dimensional string array (3 rows, 7 columns)

FOR i = 1 TO 3

FOR j = 1 TO 7

myArray$(i,j) = str$(i * j) REM str$ converts a number to a string

NEXT j

NEXT i

REM myArray$(i,j) now contains values 1 2 3 4 5 6 7

2 4 6 8 10 12 14

3 6 9 12 15 18 21

Returns the given array’s number of dimensions.

ARRAY arr(10)

var = ARRAYDIM(arr()) REM sets var to 1 as arr is one-dimensional

ARRAY myArr(2,4,4)

var = ARRAYDIM(myArr()) REM sets var to 3 as myArr is three-dimensional

ARRAYDIM (array)

Returns the given array’s dimension’s size, where array species the array and number species the

dimension. The last parameter is optional and defaults to the ﬁrst dimension if not speciﬁed.

ARRAY myArray(10)

var = ARRAYSIZE(myArray()) REM sets var to10

ARRAY myArr$(2,4)

var = ARRAYSIZE(myArr$(), 2) REM sets var to4

ARRAYSIZE (array, number)

Returns the rst character’s ASCII numerical representation. CHR$( ), converting a numerical value

to the ASCII character, is the opposite function of ASC( ).

var = ASC(“A”) REM sets var to 65

var$ = CHR$(65) REM sets var$ toA

ASC (string)

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 ... 47 48
