I need a display that is larger than the default 80 columns by 25 rows.

You can use the TERM-ATTR "COLUMNS" and "ROWS" configuration keywords to increase the number of columns and rows that the Runtime will display on the terminal.  These configuration records will need to be added to your RM/COBOL Runtime configuration file or placed in a new RM/COBOL configuration file.

For example, the following record in your configuration file will yield a screen that is 100 columns wide with 30 rows:

TERM-ATTR COLUMNS=100 ROWS=30

For more information regarding terminal configuration, please see "Chapter 10: Configuration" in the RM/COBOL User's Guide.  You can obtain the RM/COBOL User's Guide from our web site at:  http://supportline.microfocus.com/Documentation/RMCobol.asp
