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

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

Where CRPL needed…

<-UID CONST_UNITATTRIBUTE <-Value SetUnitAttribute

…most such changes can be written in PRPL with…

<-Value ->UID.Attribute

There will eventually be a page for this here.

CRPL:

<-List <-Index GetListElement
#Often, it becomes difficult to keep the ordering straight.

PRPL:

<-List[<-Index]

This will eventually be documented on the CreateList page.

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 asterix asterisk.)

<-*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?
