The SEND statement is executed after a SCREEN COBOL program has issued a BEGIN-TRANSACTION
statement, but before the program has issued an END-TRANSACTION or an ABORT-TRANSACTION statement.
Note that a program is considered to be in transaction mode if it executes a BEGIN-TRANSACTION statement,
even if the TMF parameter is OFF for the terminal or program.
These are PXMCFG command parameter settings for normal TMF and Pathway operations; SET SERVER TMF ON
must be set in the PXMCFG command file.
Although no TRANSACTION-ID is present, the PATHMON process allows the SEND statement. If the server
attempts a file lock or update operation on an audited file, a Guardian file-system error 75 is returned to the server.
How this information is returned by the server to the SCREEN COBOL requester is application dependent.
