Setting TMF Parameters
Setting TMF Parameters
The SET TERM and SET PROGRAM statements each include a TMF parameter with
an ON or OFF option:
•
TMF ON: The TCP invokes the corresponding operating system procedure for any
TMF statement issued from a SCREEN COBOL program. ON is the default setting
whether or not the TMF software is running.
•
TMF OFF: The TCP does not invoke the corresponding operating system procedure
for any TMF statement issued from a SCREEN COBOL program. Instead, the TMF
statement appears (to the SCREEN COBOL program) to complete successfully and
the program can continue to execute.
For most Pathway applications, you should use the default parameter settings for your
TERM and PROGRAM objects, whether or not the TMF software is running.
Similarly, the SET SERVER statement includes a TMF parameter with an ON or OFF
option, as described in Section 4. The setting of this parameter also affects the operation
of your SCREEN COBOL requesters and TCPs.
The following paragraphs provide further discussion of the effects of the TMF
parameter settings on your Pathway applications. Careful use of these parameters helps
to ensure the consistency of the database and to improve the reliability and performance
of your applications.
Effect of TMF Parameters on SCREEN COBOL SEND Operations
Figure 5-1 and Figure 5-2 illustrate how the various combinations of settings of the
TMF parameter in the SET SERVER, SET TERM, and SET PROGRAM statements
