Getting text from a ClearWin window

In this section:

• Introduction
• Simple programs
• Explicit ClearWin window creation
• Text output to ClearWin windows
• Getting text from a ClearWin window
• Obsolete ClearWin window functions

It is possible to extract the data placed into a ClearWin window by calling:

INTEGER FUNCTION GET_CLEARWIN_TEXT@(HWND,BUFFER,COPY)
INTEGER(7) HWND
INTEGER COPY
CHARACTER(*) BUFFER

HWND is the handle of ClearWin window in question. To obtain the handle of the default window use:

HWND=GET_DEFAULT_WINDOW@( )

If COPY is zero, the function returns the length of the required buffer but no data is copied. If COPY is 1, the data is also copied to the buffer.
