AINSERT Instruction
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:
1. All operands may be omitted to produce a record containing binary zeros in all
fields except the user data field.
2. The record written to the associated data file is described under “User-Supplied
Information Record X'0070',” in Appendix D, “Associated Data File Output” of
the HLASM Programmer's Guide.
3. If you do not specify the ADATA assembler option, or the GOFF(ADATA) or the
XOBJECT(ADATA) assembler option (MVS or CMS), the assembler only
checks the syntax of an ADATA instruction, and prints it in the assembler
listing.
4. The assembler writes associated data records to the SYSADATA (MVS or
CMS), or the SYSADAT (VSE) file if the ADATA assembler option has been
specified.
AINSERT Instruction
The AINSERT instruction inserts statements into the input stream. These
statements are queued in an internal buffer until the macro generator has
completed expanding the current outermost macro instruction. At that point the
internal buffer queue provides the next statement or statements. An operand
controls the sequence of the statements within the internal buffer queue.
Note: While inserted statements may be placed at either end of the buffer queue,
the statements are removed only from the front of the buffer queue.

sequence_symbol
is a sequence symbol.
statement
is the statement stored in the internal buffer. It may be any characters
enclosed in single quotation marks.
The rules that apply to this character string are:
Variable symbols are allowed.
The string may be up to 80 characters in length. If the string is longer than
80 characters, only the first 80 characters are used. The rest of the string
is ignored.
BACK
The statement is placed at the back of the internal buffer.
