Procedures as library elements

Since the introduction of the COMPILE-PROCEDURE command, S procedures that are stored as PLAM library elements can be of element type J or SYSJ. Element type J is recommended for text procedures and element type SYSJ for compiled procedures. The element type can be specified when calling with the CALL-PROCEDURE or INCLUDE-PROCEDURE command. The default value is TYPE=*STD, i.e. only when an element of type SYSJ does not exist will the element of type J be called. An additional library access is required when this method is used. The additional access can be prevented when the caller knows the element type and also explicitly specifies it.
