10. Hercules 3270 Logo
10.1 Function
The Hercules 3270 logo is the initial welcome screen that is presented when a 3270 terminal connects to
a Hercules 3270 device. While in previous releases of Hercules this logo screen was hardcoded it can
now be customized.
The customized logo is stored in a plain text file which contains positioning orders, attributes and supports
variable substitutions. Each line in the text file represents either an order statement or a plain text line. If
no logo file is specified then Hercules uses a built-in default logo. Upon startup Hercules will first look in
the current directory for a file called "herclogo.txt". The name of the logo file can also be specified as a
startup option by using the "-b" flag. The file may also be specified using the "LOGOFILE" system para-
meter or can be changed during Hercules operation using the "HERCLOGO" console command.
10.2 Order Commands
Order commands are used to set the current buffer position, set the highlight and/or protected attributes,
to force a skip to a new line and to specify text alignment.
