Syntax

this referent

this referent is used in a repeat over referents loop to refer to the current referent.

this referent can be used in many ways:

• in actions modified by a using referent prefix, wherever a string expression is expected. The current value of the selected referent is returned.
• to change the value of the current referent (for example, set this referent to).
• to obtain the key of the current referent (key of this referent). The selected referent is guaranteed to have a key (unlike integers, streams and shelves) because it must exist, and all referents have a key.
• to determine the status of the selected referent (this referent (is | isnt) attached). The test succeeds if the selected referent has been opened or defined (with the set action, for example) at some time.
