**CIGAL Reference Manual, Chapter 3 (Functions): array**
===== Array -- Allocate memory for an array variable =====
**usage: arrayvarb = array(leng)**

The ARRAY command sets the length and allocates storage space for dynamic array
variables (i.e., for array variables originally declared without a length
specification -- see [[jvs:cigal:manual:chapter2:declare|DECLARE(2)]]).  This command has no effect on static array
variables, for which the storage space is fixed.

The LENG argument is necessary and indicates the number of requested storage
elements.  The total memory space allocated depends on the word size originally
specified by the DECLARE command.   ARRAY first releases any memory previously
allocated to ARRAYVARB and then allocates new memory if enough is available,
otherwise an error message is printed.  Memory allocated by the ARRAY command
remains dynamic and can be changed by subsequent calls to ARRAY, or ACCEPT,
or by the assignment operator (%%=)%%.
