                     Line-A  Function Calling Procedure


Line-A functions are called by simply inserting the opcode into the
instruction stream. For example, the 'Hide Mouse' function is called with
the following assembly language instruction:

                        dc.w    $A00A

Generally, the Line-A initialization function is called ($A000) and the
address of the variable and/or font header tables are stored. Prior to
each Line-A call variables are set as explained in the Line-A Function
Reference and the function is then called. There is no method of error
reporting available.
