PROGRAM-ID. SYIXSAM2.
****** SYIXSAM2 - RPC REQUEST APPLICATION - COBOL2 - IMS ********
*
* TRANID: SYIXSAM2
* PROGRAM: SYIXSAM2
* PLAN NAME: N/A
* FILES: N/A
* TABLES: N/A
*
* This program is an example of a long-running transaction.
* It may also be used to stress test IMS Open Server. The
* program is executed via isql. The first parameter is
* a one byte character that is used to set up a reply
* row. The second parameter is the number of rows to
* return to the client.
*
* To execute from isql type:
*
* >isql -Usa -Sservername
*
* >exec SYIXSAM2 X, 100
*
* >go
*
* To end SYIXSAM2 type:
*
* >exec SYIXSAM2 X,0
*
* >go
*
* The SYIXSAM2 tran returns a 80 byte row containing the name
* client that initiated the RPC and a 71 byte pattern.
*
* Server Library calls:
*
* TDACCEPT accept request from client
* TDESCRIB describe a column
* TDFREE free TDPROC structure
* TDGETREQ get next set of parms
* TDINIT establish environment
* TDRCVPRM retrieve rpc parameter from client
* TDSNDDON send results-completion to client
* TDSNDMSG send message to client
* TDSNDROW send row to client
* TDSTATUS get status information
* TDSETPT pass type of program to gwlib
* TDTERM clean up control blocks
* CHANGE ACTIVITY:
* 9/93 - created for IMS MSP
