Cursor Restore (CSR)<br />
The CSR record restores the cursor position to the last position stored by<br />
a CSS record for the specified number. The restore number in this record<br />
references the save number in the CSS record.<br />
If a cursor position was not stored for the number specified in the CSR<br />
record, the cursor is set to the default position (0,0).<br />
The CSR record does not reset the saved cursor position it restores.<br />
Successive CSR records for the same position number, without an<br />
intermediate CSS record, set the cursor to the same saved position.<br />
1-2 2 Record Length The length of this record, in binary, including the record length<br />
field. For example, hex 00 05 specifies a record length of 5 bytes.<br />
3 1 Cyclic Record Count A binary cyclic record count using modulo 256. Each record in the<br />
job is counted, starting with hex 01 for the first record. The 255th<br />
record is hex FF and the 256th record is hex 00. This count is used<br />
to verify record sequence.<br />
4 1 Control Code A binary code that identifies the record type. A value of hex 37<br />
identifies the CSR record.<br />
5 1 Restore Number A binary number that identifies the saved cursor position. The<br />
range is 0-15, allowing 15 cursor positions to be restored. Restore<br />
number 0 always sets the cursor position to 0,0.<br />
