/* */
/* General: */
/* This is an example ACSE/Presentation program. */
/* It illustrates how to call the APS procedures. */
/* Some liberties have been taken in error checking; */
/* real applications would include error checking. */
/* This program calls the APS procedures in wait mode. */
/* */
/* OSI/AS Configuration: */
/* 1) The OSI manager process name is $OMGR. */
/* 2) ENTRY #APPL.APPL1 is defined (this program). */
/* 3) ENTRY #APPL.APPL2 is defined (for EXAPSC2B). */
/* 4) Either session version 1 or session version 2 */
/* can be configured. */
/* */
/* To run: */
/* 1) Be sure to run EXAPSC2B (APPL2) first. (It will */
/* issue an attach and wait for a connect */
/* indication). */
/* 2) Run this application second. */
/* */
/* This program does the following: */
/* 1) Issues an ACSE associate request. */
/* 2) Waits for the ACSE associate confirm. */
/* 3) Issues a P-DATA request plus a P-GIVE-TOKENS */
/* request using basic concatenation. */
/* 4) Waits for a P-DATA indication. */
/* 5) Waits for an ACSE release indication. */
/* 6) Issues an ACSE release response. */
