Set Buffer Address (SBA)
Function
The SBA order specifies a new buffer address from which operations are to
start or continue. You can use the SBA order to:
S Write data into various areas of the buffer.
S Precede another order in the data stream to specify the starting address
for an RA order.
S Specify the address at which an attribute byte is stored by a SF order.
Restrictions
A parameter error is posted when:
S Fewer than two bytes follow the order.
S The row address is equal to 0 or greater than 24.
S Thecolumnsizeequals0orisgreaterthan80.
Default. When the SBA is not specified in the WTD command, the data
starts at row 1, column 1. This is where the WTD command initialized it.
Format
The SBA order takes the following form:
SBA Order Row Address Column Address
Hex 11 Hex 01 Hex 01
Row addresses begin with 1, as do column addresses. However, the termi-
nalacceptscolumnaddresshex00andtranslatesittocolumn1.
