Specifying input parameters
Using LCDS Print Description Language
2-15
•
If a block length is specified that is less than the minimum
block length that is found on the tape, the system allocates
input buffers, which are sized to the minimum tape block
length. It is wise to specify the maximum block length in the
JSL, so that input buffers are large enough to handle the
largest block. However, specifying the maximum block length
in the JSL may slow performance. If the actual tape block
length is smaller than the JSL block length, no error message
is reported; otherwise, an error is displayed.
•
The length on a 4 by 3 packed format tape is the number of 6-
bit bytes or characters in the tape block.
BLOCK LMULT
Specifies a multiplication factor that is applied to the contents of
the block length field to determine the true block length.
Syntax
BLOCK LMULT = value
Options
Default
1
BLOCK LTHFLD
Specifies the length of the field that contains the block length.
Syntax
BLOCK LTHFLD = size
Options
Table 2-9. BLOCK LMULT parameter options and definitions
Option
Definition
value
An integer in the range of 1 to 15 that is multiplied by the value in the length
field (refer to LENGTH parameter) to compute the number of bytes in the block.
Table 2-10. BLOCK LTHFLD parameter options and definitions
Option
Definition
size
An integer from 0 to 5 that specifies in bytes the length of the field that contains
the block length.
