Commodore CBM - DIM

Examples:
10
DATA NAME."C.D."
50 DATA 1
E6.-1 O.XYZ
Defines two string variables.
Defines
two numeric variables and
one string variable.
DIM
The Dimension statement (DIM) allocates space for arrOlYs.
Format:
DIM
where:
{
var(j)
var(j). var(j)
.... var(j)
Dimension one array.
Dimension multiple arrays.
DIM statement usage
in program mode.
var
is a numeric or string variable name.
is a constant. variable or expression represent-
ing the subscript or subscripts of the array. in
the form:
var(j) Single-dimension array
vadi,j} Two-dimension array
vadi,j.k .... } Multiple-dimension array
Refer to
"Arrays" in Chapter 3 for a complete description of array formats.
Arrays
with more than eleven elements must be dimensioned in a DIM
statement. The DIM statement must be encountered once. and only once. in pro-
gram execution before any statement calls
an element of the array. Arrays of
eleven elements or less (subscripts 0 through 10 for a one-dimensional array) may
be used without being dimensioned by a DIM statement; for su ch arrays. eleven
array spaces are allocated
when the first array element is encountered.
If the array
is dimensioned more than once. or if an array having more than
eleven elements
is not dimensioned. a ?REDIM'ED ARRAY error occurs and the
program
is aborted. A CLR statement allows a Dimension statement to be reex-
ecuted: this
is not normally done. however.
DIM may be given in either immediate or program mode.
Examples:
10 DIM A(3)
45 DIM X$(44.2)
1000 DIM
MU(N.3*B). N(12)
