Memory Allocation
=================

Program Limits And Memory Usage
-------------------------------

#. **Ranges**

   | Variables: ±9.99999E±126
   | String arrays: Up to 2544 characters per string
   | Line numbers: 0-65535 inclusive
   | Program line length: Up to 254 characters including line number

#. **Precision**

   | Single precision variables have 6 digit resolution.
   | Double precision variables have 14 digit resolution.

#. **Memory overhead**

   Program lines require 4 bytes minimum, as follows:

   | Line number: 2 bytes
   | Line length: 1 byte
   | Carriage return: 1 byte

Also each reserved word, operator, variable name character, special
character and constant character requires 1 byte. Maximum program size
in present versions: 54K Bytes (Page 0)

Dynamic (Run-Time) Memory Allocation
------------------------------------

#. **Symbol Table**

   Entries occupy: 7 Bytes each Maximum symbol table size: 16K Bytes

#. **Single Precision Array**

   DIM A(X) occupies (X+1)*5+7 Bytes

#. **Double Precision Array**

   DIM A!(X) occupies (X+1)*9+7 Bytes

#. **String Array Elements**

   DIM A$(X,N) occupies (X+1)*N+7 Bytes

#. **Array Size**

   Maximum number of elements in an array is 16,383.
