DIM
Field of Application Statement specifying the dimensions of an array.
Syntax DIM<<nvar>|<svar>>(<nexp
1
>[,<nexp
2
>...])...
...[,<<nvar>|<svar>>(<nexp
1
>[,<nexp
2
>...])]
<nvar>|<svar> is the name of the array.
<nexp
1
> is the max. subscript value for the fi rst dimension.
<nexp
2-10
> are, optionally, the max. subscript value for the following
dimensions (No. 2-10).
Remarks An array is created by entering a variable followed by a number of
subscripts (max 10) separated by commas. All the subscripts are enclosed
by parentheses. Each subscript represents a dimension. The number of
subscripts in an array variable, the fi rst time (regardless of line number) it
is referred to, decides its number of dimensions. The number of elements in
each dimension is by default restricted to four (No. 0-3).
If more than 4 elements in any dimension is desired, a DIM statement must be
issued. Note that 0 = 1:st element, 1 = 2:nd element, etc.
For example ARRAY$(1,2,3) creates a three-dimensional array, where the
dimensions each contain 4 elements (0-3) respectively. This corresponds to
the statement DIM ARRAY$(3,3,3).
It is not possible to change the number of dimensions of an array that
already has been created during runtime. (Error 57, “Subscript out of
range” will occur.)
Considering the printer’s limited memory and other practical reasons, be
careful not to make the arrays larger than necessary. A DIM statement can be
used to limit the amount of memory set aside for the array.
Examples This example creates an array containing three dimensions with 13
elements each:
100 DIM NAME$(12,12,12)
Here, two one-dimensional arrays are created on the same program line:
10 DIM PRODUCT$(15), PRICE%(12)
20 PRODUCT$(2)="PRINTER"
30 PRICE%(2)=1995
40 PRINT PRODUCT$(2);" $";PRICE%(2)
RUN
yields:
PRINTER $1995
