DIM name {(|[} limit_0 [, limit_1] ... {)|]}

Allocates memory for arrays. The DIM statement also fixes the number of indices of the array. Unlike Microsoft BASIC, an array can be reallocated.

• name is a legal variable name specifying the array to be allocated.
• limit_0, limit_1, ... are numeric expressions that specify the greatest index allowed at that position.

The size of arrays is limited by the available BASIC memory.

• An index is empty: Syntax error.
• An index is missing at the end: Missing operand.
• limit_0, limit_1, ... have a string value: Type mismatch.
• limit_0, limit_1, ... are not within [-32768 to 32767]: Overflow.
• limit_0, limit_1, ... are negative: Illegal function call.
• The array exceeds the size of available variable space: Out of memory.
