GSHAPE Abbr. gS
GSHAPE string variable, coordinates, mode
GSHAPE (GetSH APE), which is the opposite of the SSH APE (SaveSHAPE)
command, retrieves and displays a graphic screen area saved by an SSHAPE
command. You can use SSHAPE and GSHAPE in any graphic mode to store
and retrieve a rectangular section of the screen that is up to 255 text-sized
characters long.
These graphic screen areas are saved as text-string values in memory. You use a
text-string variable to identify the screen area, just as you use a variable to
identify any type of value.
After you save a screen area with SSHAPE, you can display it anywhere on the
graphic screen. When you retrieve the area in the GSHAPE command, you give
the screen location where you want the area to be displayed.
Parameters: string variable, top corner coordinate, display mode
1. The string variable is the name assigned to the graphic screen area saved
with the SSHAPE command. Retrieve the area by using the same string-variable
name used in the SSHAPE command.
2. Display a copy of the saved graphic screen area anywhere on the screen by
giving the coordinates of the top left corner of the screen area where you want the
drawing to appear.
3. When you retrieve the saved area, you can choose one of the five options for
displaying it.
0 display duplicate of saved area (default)
1 display saved area in reversed colors
2 OR saved area with current area
3 AND saved area with current area
4 XOR saved area with current area
Option 0, which is the default value for this parameter, draws the area as you
saved it.
