Sample data block
A sample GRASP data block is shown in figure 3-2.
Figure 3-2. Sample GRASP data block
Note:
1. This block does not contain a line-up record. If it did, the line-up
record would be in the first logical record position and it would
have the same format as all other logical records in the block.
2. The identification segment length byte includes itself in the
length count, while the data record length byte gives the length
of the print data within the logical record.
3. The carriage control bytes shown in this example could be used
directly without resetting bit 5 (it is already 0). “0B” indicates
space 1 immediate (no printing), “09” indicates space 1 after
printing, and so on.
4. CCW indicates channel control word.
GRASP carriage control conventions
GRASP carriage control is identical to IBM 1403 carriage control
except bit five (counting from the left of the byte) is set. This is
equivalent to adding binary four to each of the IBM 1403 control
codes. For example, GRASP code X'0D' is processed as 1403 code
X'09', or “print and space one line.”
