DIM

Syntax: DIM name(size)[,name(size)...]

Where: name = Any valid variable name

size = 1 to 255 elem ents

Function: Reserves storage for single-dimension array.

Mode: Command, run

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

Cards: All

DESCRIPTION

The maxim um number of array elements is 255, accessed as name(0) through name(254). CLEAR, NEW , or

RUN com mands de-a llocat e all array storage. T he default size of und eclared arrays is 10 (i.e . 11 elem ents).

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

ERROR

ARRAY SIZE When size >255

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)=AIN(0)

1010 LEVEL(PTR)=AIN(1)

1020 PTR=PTR+1

1030 RETI

1 2 ... 43 44 45 46 47 48 49 50 51 52 53 ... 162 163
