SAS/FSP Software Procedures Guide

Concurrent Window Commands

You can open multiple windows from a single invocation of the FSLETTER or FSVIEW procedure. These windows are referred to as concurrent windows. The following commands are useful for managing concurrent windows in FSLETTER and FSVIEW sessions:

SWAP

moves the cursor to the next concurrent window and activates that window.

WREGION <start-row start-column rows columns> WREGION CLEAR

specifies the area of the display that the next concurrent window that is opened by an EDIT or BROWSE command will occupy.

Note: The WREGION command affects only the next window that is opened, not all subsequent windows. [cautionend]

Specify the starting row and column for the upper left corner of the new window and the window's size in rows and columns. You can use the global WSIZE command to determine the size of the current window.

Note: In character-based display environments, the area of the window that is available for procedure output is four lines and two rows less than the amount you specify in the rows and columns arguments. Remember that the top and bottom window borders, the command line, and the message line occupy a total of four rows, and the left and right window borders occupy two columns. For example, the following command would cause the next window to occupy the bottom half of a 24-line by 80-column display:

wregion 13 1 12 80

This restriction is not applicable to graphical windowing environments. [cautionend]

Use the WREGION CLEAR command to clear any previous WREGION setting and return to the default layout in which concurrent windows partially overlap in a staggered pattern.

Use the WREGION command with no arguments to display the window's current region setting on the window's message line.
