COPY_FOR_VIEW

Programming Guide

Changes the transaction manager to view mode
int sm_tm_command ("COPY_FOR_VIEW");

Description

COPY_FOR_VIEW makes view the current mode. After you select COPY_FOR_VIEW, the transaction manager disables before image processing. Changes to the data currently on the screen no longer generate updates to the data base with a SAVE command.
Push buttons and menu selections for the COPY_FOR_VIEW command can choose to set the class property to continue_button. By default, continue_button is active in view or update modes.

Sequence

COPY_FOR_VIEW is available after any command.

Events

The following requests can be generated by the COPY_FO+R_VIEW command to as certain whether the changes from the previous command have been saved and, if desired, discard those changes:

TM_PRE_CLOSE (described under CLOSE)

TM_CLOSE (described under CLOSE)

TM_QUERY (described under CLOSE)

TM_DISCARD (described under CLOSE)
