* 
*     2. FUNCTIONAL DESCRIPTION 
*        CREATE ACNB AND UPDATE ASSOCIATED HEADER AND ENTRY 
*        PARAMETERS.  ALSO UPDATE ACNT ENTRY. 
* 
*     3. METHOD 
*        ALLOCATE A CONNECTION NUMBER.
*        CHECK IF APPLICATION CONNECTION TABLE (ACNT) IS FULL.
*        IF FULL, REQUEST FOR AN EXTENDED BUFFER (CALLING MGETS)
*        AND UPDATE ACNT ADDRESS IN ACB.  UPDATE ACNT HEADER
*        AND INITIALIZE ENTRY PARAMETERS.  REQUEST A
*        BUFFER FOR THE APPLICATION CONNECTION BLOCK(ACNB). 
*        FILL IN INFORMATION FOR ACNB AND LINK TO ACNT AND NCNB.
*        UPDATE TOTAL NUMBER OF CONNECTIONS CURRENTLY HELD BY 
*        THIS APPLICATION IN THE ACB. 
* 
*     4. ENTRY PARAMETERS 
*        PARAMP1 - ADDRESS OF SM BUFFER (TEXT)  ICN/TE/R
*        PARAMP2 - ACB ADDRESS
* 
*     5. EXIT PARAMETERS
*        PARAMP3 - ACNB ADDRESS 
*        PARAMP4 - ACNT ADDRESS 
* 
*     6. COMDECKS CALLED AND SYMPL TEXTS USED
