applications that use a specific carriage control character to define page
boundaries (for example, skip to channel 1), consider defining the value of
the carriage control character as one of the TRIGGERn parameters. The
supported range of values for
column
are 1–32 756. If the specified value
exceeds the physical length of the record, ACIF reports an error condition
and terminates processing.
length
Specifies the number of contiguous bytes (characters) starting at
column
that compose this field. The supported range of values for
length
is 1–250.
The field can extend outside the record length, as long as the column
where it begins lies within record length. In this case, ACIF adds padding
blanks (X'40') to fill out the record. If the field begins outside the maximum
length of the record, ACIF reports an error condition and terminates
processing.
{
‘literal value’
| X'literal value'}
Specifies the literal (constant) value of the FIELDn parameter. This value
can be specified either as character data or as hexadecimal data. The
literal value can be 1–250 bytes in length. ACIF does not perform any
validity checking on the actual content of the supplied data.
EXAMPLE
FIELD1=,2,2
FIELD2=5,5,1
FIELD3=–15,3,5
FIELD4=‘444663821’
FIELD5=X'1'
The first field in the example is located in the indexing anchor record
(TRIGGER1). It is 20 bytes in length, starting at the second byte of the
record. The second field is located five records down from the indexing
anchor record. It is 10 bytes in length, starting at the fifth byte of the record.
The third field is located 15 records before the indexing anchor record. It is
5 bytes in length, starting at byte 30. The fourth and fifth fields are literal
(constant) values. One is specified as character data (for example,
EBCDIC), and the other is hexadecimal data.
ACIF allows fields to be defined but never referenced as part of an index.
Because ACIF requires either a field or TRIGGER to appear on the first
page of a logical document, unless the INDEXSTARTBY parameter is
used, you can satisfy this requirement by defining a “DUMMY” field. This
DUMMY field allows ACIF to determine the beginning page of a logical
document, but it is not used as part of an index. If you specify the
INDEXSTARTBY parameter, start counting on the first page on which you
have a valid field, not a DUMMY field.
