=====Upgrade Notes=====

PRPL implements some of the features which CRPL did not have, save by workarounds.

===Accessor Notation===
Accessor Notation (AcNot) streamlines the process of changing unit properties.

Where CRPL needed...
<code>
<-UID CONST_UNITATTRIBUTE <-Value SetUnitAttribute
</code>
...most such changes can be written in PRPL with...
<code>
<-Value ->UID.Attribute
</code>

There will eventually be a page for this [[.:accessornotation|here]].

===List Accessing===
CRPL:
<code>
<-List <-Index GetListElement
#Often, it becomes difficult to keep the ordering straight.
</code>

PRPL:
<code>
<-List[<-Index]
</code>

This will eventually be documented on the [[.:createlist|CreateList]] page.

===Global Variables===
CRPL had no built-in capacity to handle map-global variables, although a slow and difficult implementation could be achieved through a "watcher" Core or lists.

PRPL, on the other hand, makes it almost as easy to use these as to use standard variables. (It's a matter of an <del>asterix</del> asterisk.)

<code>
<-*Var #Read
->*Var #Write
--*Var #Delete
-?*Var #Check existence

<-VarName ->!* #Ref-read (and similarly for the other ref- operations)

ClearGlobals #Same as ClearLocals. Need I say more?
</code>
