 +VioReadCellStr (CellStr, Length, Row, Column, VioHandle) 
 +</code> 
 +===== Parameters =====
  
-==Parameters== +  * CellStr ([[PCH]]) - output : Address of the buffer where the cell string is returned. 
-;CellStr (PCH) - output : Address of the buffer where the cell string is returned. +  * Length ([[PUSHORT]]) - input/output : Address of the buffer length in bytes. Length must take into account that each character-attribute(s) entry in the buffer is 2 or 4 bytes. If the length of the buffer is not sufficient, the last entry is not complete. 
-;Length (PUSHORT) - input/output : Address of the buffer length in bytes. Length must take into account that each character-attribute(s) entry in the buffer is 2 or 4 bytes. If the length of the buffer is not sufficient, the last entry is not complete. +  * Row ([[USHORT]]) - input : Starting row of the field to read, 0 is the top row. 
-;Row (USHORT) - input : Starting row of the field to read, 0 is the top row. +  * Column ([[USHORT]]) - input : Starting column of the field to read, 0 is the leftmost column. 
-;Column (USHORT) - input : Starting column of the field to read, 0 is the leftmost column. +  * VioHandle ([[HVIO]]) - input : This must be zero unless the caller is a Presentation Manager application, in which case it must be the value returned by VioGetPs. 
-;VioHandle (HVIO) - input : This must be zero unless the caller is a Presentation Manager application, in which case it must be the value returned by VioGetPs.+

 +===== Remarks =====
  
-==Return Code== 
 If a string read comes to the end of the line and is not complete, the string read continues at the beginning of the next line. If the read comes to the end of the screen and is not complete, the read terminates and the length is set to the length of the buffer that was filled. If a string read comes to the end of the line and is not complete, the string read continues at the beginning of the next line. If the read comes to the end of the screen and is not complete, the read terminates and the length is set to the length of the buffer that was filled.
