 VioWrtCharStr (CharStr, Length, Row, Column, VioHandle) 

• CharStr (PCH) - input : Address of the character string to be written.
• Length (USHORT) - input : Length, in bytes, of the character string.
• Row (USHORT) - input : Starting cursor row.
• Column (USHORT) - input : Starting cursor 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.

rc (USHORT) - return

Return code descriptions are:
