<h3><font color=#C00040>TopView - SEND MESSAGE - READ - READ NEXT LOGICAL LINE OF WINDOW</font></h3>
<PRE>
AH = 12h
BH = 04h
BL = window to read from
00h handle is DWORD on top of stack
01h use calling task's default window
0Ch (DV 2.26+) default window of task owning handle on top of stack
0Dh (DV 2.26+) default window of parent task of current task<br>
<p><b>Return:</b><br>STACK: DWORD number of bytes read
DWORD address of buffer
</PRE>
<p><b>Notes:</b>
Reading starts at the current logical cursor position; the cursor is
updated to point at the character following the last one read.
Any translucent blanks (FFh) which are visible on screen are changed
to the character which is seen through them.
The string produced by the read is placed in an input buffer which may
be reused by the next READ or READN of a window.
Window stream opcodes D8h and D9h determine whether the read returns
characters or attributes
