up to four values may be specified, separated by commas. If a value
is omitted, the field written to the associated data file contains
binary zeros. You must code a comma in the operand for each omitted
value. If specified, value1 through value4 must be a
decimal self-defining term with a value in the range
-231 to +231-1.
character_string
is a character string up to 255 bytes long, enclosed in single
quotes. If omitted, the length of the user data field in the associated
data file is set to zero.
Notes:
All operands may be omitted to produce a record containing
binary zeros in all fields except the user data field.
If you do not specify the ADATA assembler option, or the
GOFF(ADATA) or the XOBJECT(ADATA)
assembler option (z/OS or CMS),
the assembler only checks the syntax of
an ADATA instruction, and prints it in the assembler listing.
The assembler writes associated data records
to the SYSADATA (z/OS or CMS),
or the SYSADAT (z/VSE) file
if the ADATA assembler option has been specified.
