/* This file is a replacement for the engine call of ALLOC_STRING
|
|
* The main difference is that a string will not be allocated twice
|
|
* as to try to avoid wasting the HL zone space.
|
|
*
|
|
* NOTE: The lookup uses strcmp() in a linked list! It is not fast
|
|
* Its implementation in the NS module is on rarely used
|
|
* natives.
