Explanation
The STATE library attribute returns the logical state of one of the connections of a connection library.
When a program reads the STATE attribute, the program must specify a connection index unless the connection library was declared with the SINGLE keyword. For example, the following ALGOL statement reads the STATE attribute for connection 3 of connection library CLIB:
IF LIBRARY(CLIB[3]).STATE = VALUE(NOTLINKED) THEN...
The following are the possible STATE values and their meanings:

Integer Value |
Meaning |
|---|---|---|
|
NOTLINKED |
1 |
The connection is not linked. |
|
LINKING |
2 |
Linkage is initiated but is not complete. The APPROVAL procedure, if any, is called. However, no procedure linkages are established yet. |
|
LINKED |
3 |
The connection is now fully linked. |
|
DELINKING |
4 |
The connection is in the process of being delinked. |
The current state of a connection is also automatically passed to the CHANGE procedure, if any. Refer to CHANGE earlier in this section.
