Statement DIM

Allocate a zero-based integer array.

Syntax

DIM array(upper-bound)

Parameters

Parameter	Meaning
`array`	One letter A–Z; independent from its scalar.
`upper-bound`	Runtime integer 0–75, subject to remaining total capacity.

Behavior

DIM A(9) allocates ten zeroed words, indexed 0 through 9. All arrays share 76 elements. An array may be dimensioned once per execution. Out-of-range access, missing DIM, repeated DIM or insufficient capacity returns status 39.

Example

DIM A(3)
FOR I=0 TO 3
A(I)=I*I
NEXT I
PRINT A(3)

Limits and diagnostics

One dimension and one declaration per statement. No REDIM, arrays of strings or implicit allocation.
