5. Executive Primitives

5a. Primary Links

5a1. These require the HOST number as a parameter.

5a1a. Establish primary link

5a1b. Connect controlling teletype to primary link

5a1c. INPUT/OUTPUT over primary link

5a1d. Interrogate status of primary link

5a1d1. Don't know what, exactly, this should do, but it seems as though it might be useful.

5a1e. Disconnect controlling teletype from primary link

5a1f. Kill primary link

5b. Auxilliary Links.

5b1. Establish auxilliary link.

5b1a. requires the HOST number as a parameter

5b1b. It returns a logical link number which is similar to a file index. It is this number which is passed to all of the other Auxilliary routines as a parameter.

5b2. INPUT/OUTPUT over auxilliary link

5b3. Interrogate status auxilliary link.

5b3a. Don't know what, exactly, this should do, but it seems as though it might be useful.

5b4. Kill auxilliary link.

5c. Special executive functions

5c1. Transparent. INPUT/OUTPUT over link

5c1a. This may be used to do block I/O transfers over a link

5c1b. The function of the monitor in this instance is to transfer a buffer directly to its IMP

5c1c. At does not modify it in any way

5c1c1. This means that the header and other control information must be in the buffer.

5c1d. The indended use of this is for network debugging.
