DIM

Syntax: DIM

name

(

size

)[,

name

(

size

)...]

Where:

name

= Any valid variable name

size

= 1 to 255 elements

Function: Reserves storage for single-dimension array.

Mode: Command, run

Use: DIM FLOW(200) : REM dimensions a 200 element array called FLOW

DESCRIPTION

The maximum number of array elements is 255, accessed as

name

(0) through

name

(254). CLEAR, NEW, or

RUN commands de-allocate all array storage. The default size of undeclared arrays is 10 (i.e. 11 elements).

An array cannot be redimensioned after it has been dimensioned. Memory required for an array is ((integer

size + 1) * 6). Array A(99) requires 600 bytes of memory. Available memory typically limits the size and

number of dimensioned arrays.

STRING, CLEAR

EXAMPLE

10 DIM FLOW(200), LEVEL(200)

20 ONTICK 1,1000

30 IF PTR < 200 THEN 30

40 ONTICK 0,1000

50 FOR N=0 TO 199

60 PRINT FLOW(N),LEVEL(N)

70 NEXT

80 END

1000 FLOW(PTR)=REGERAD(7001)

1010 LEVEL(PTR)=REGREAD(3)

1020 PTR=PTR+1

1030 RETI

1 2 ... 18 19 20 21 22 23 24 25 26 27 28 ... 83 84
