7.6.4 Transient list file extension
Transient list files always use the “.TLS” extension. This extension is
reserved for this purpose and no other files using the same extension should
be stored in the same subdirectory as used to hold transient list programs.
Transient list files are stored in simple ASCII formats to facilitate
documentation and transfer of transient list programs through email systems.
Nevertheless, the user is discouraged from editing these files with a text
editor. The file format for this file type is provided in section 12.2 of this
manual.
7.6.5 Automatic save on OK
Because entering transient lists can be time consuming, it is important
not to accidentally loose information when the Transient window is closed.
To prevent this from happening, the LSGUI program will automatically save
the contents of all the parameter fields any time the button is
clicked. The data is stored to a default file called “LSGUI.DTL” in the
program directory. Any time the Transient screen is opened, the LSGUI
looks for the presence of this file. If it can be found, its contents are loaded in
the transient data entry fields. Consequently, if the user exits the transient
screen using the button and then re-enters it, all data will be
restored, even if no Save List operation was performed.
The same is not true when the transient screen is closed with the
button, the ESC key or the Close sub-menu in the control box
menu. (also activated with the ALT-F4 key combination.
