Capturing a rectangular area of the host terminal
When the continuous attribute is false (this is the default value), the macro runtime treats the two pairs of row and column values as the upper left and lower right corners (inclusive) of a rectangular block of text. The rectangular block can be as small as one character or as large as the entire application window.
- Initializes the result string to an empty string
- Reads the rectangular block of text row by row, concatenating each row to the result string
- Stores the result string in the specified variable
.8..Outlist.....Display, delete, or prin
.9..Commands....Create/change an applica
.10.Reserved....This option reserved for
In addition, suppose
that the macro runtime is about to perform an Extract action with
the following settings:
- The continuous attribute is false.
- The row and column pairs are (16, 5) (the 'O' of Outlist) and (18, 12) (the 'd' of 'Reserved').
- The extraction name is 'Extract1'.
- The data plane is TEXT_PLANE.
- The string variable $strTmp$ is the variable in which the result string is to be stored.
Because the continuous attribute is false, the macro runtime treats the row and column pairs as marking a rectangular block of text, with the upper left corner at row 16 and column 5 and the lower right corner at row 18 and column 12.
