Assembler File Definitions

Assembler File Definitions use Assembler syntax to describe records in a table definition. An Assembler file can contain multiple record definitions. Record description entries begin with a DSECT keyword and can contain elementary items.

You can import both Assembler source files and listing files into the InfoSphere® DataStage® repository. Assembler source files have the following default values:

The begin column is at column 1.
The end column is at the begin column plus 70.
The continuation column is at the begin column plus 71.
The continue column is at the begin column plus 15.

Default values for Assembler listing files are:

The begin column is at column 42.
The end column is at the begin column plus 70.
The continuation column is at the begin column plus 71.
The continue column is at the begin column plus 15.
Any statements before the begin column are not processed.
Any statements after the continuation indicator are not processed.
Note: Listing file offsets are calculated using the IBM® Assembler. If you use another vendor's Assembler, adjustments might be needed before import.

Comments must be designated with an asterisk in the begin column and must lie within the statement field. They cannot appear between an instruction statement and its continuation lines. Comments that appear before the first DSECT keyword become the long description for the table. The fully qualified path and file name of the AsmFD, as well as the current date and time, are saved as the short description for the table.

The import process creates an InfoSphere DataStage table of type QSAM_SEQ_ COMPLEX. Assembler data types are converted to COBOL native data types during capture, as described in Table 1.

Table 1. Assembler Data Type Conversion
Assembler Type	COBOL Native Type	COBOL Usage Representation	SQL Type
B	CHARACTER	PIC X(n)¹	Char
C	CHARACTER	PIC X(n)	Char
D	FLOAT	COMP-2	Decimal
E	FLOAT	COMP-1	Decimal
F	BINARY	PIC S9(9) COMP	Integer
G	NCHAR	PIC N(n)	NChar
H	BINARY	PIC S9(4) COMP	SmallInt
L	CHARACTER	PIC X(n)	Char
P	DECIMAL	COMP-3 SIGNED	Decimal
X	CHARACTER	PIC X(n)	Char
Z	DISPLAY NUMERIC	PIC S9(n)	Decimal

¹(n) is equal to the number of bytes.
