Numeric capabilities take a numeric argument; for example, the number of columns on the terminal screen.
The format for a numeric capability field is as follows:
|
NUMERIC {numeric-capability = value} [,...] |
Following are the meanings of the elements:
| OpenVMS Name | Used by SMG | Description |
|---|---|---|
| COLUMNS | Y | Specifies the number of columns in a line. |
| CR_FILL | N | Specifies the number of fill characters needed after a carriage return. |
| LF_FILL | N | Specifies the number of fill characters needed after a line feed. |
| FRAME | N | Controls the number of data bits expected by the terminal driver for every character that is input or output (value must be between 5 and 8, inclusive). |
| NUMBER_FN_KEYS | N | Specifies the number of function keys available. |
| PRIVATE_NUM_1 to 10 | N | If set, these fields denote user-defined capabilities 1 through 10. |
| ROWS | N | Specifies the number of rows on the screen. |
| WIDE_SCREEN_COLUMNS | Y | Specifies the number of columns available in wide mode. |
For example, the following TERMTABLE entry describes two characteristics of a VT300-series terminal:
NAME = "VT300_series"
NUMERIC
rows = 24, columns = 80
|
String capability fields provide several features. They let you do the following:
