Input and output files
Depending on the options in effect, High Level Assembler requires the
files as shown in Figure 50.

High Level Assembler requires the following files:
- SYSIN
- An input file containing the source statements to be processed.
- SYSLIB
- A file containing macro definitions (for macro definitions not
defined in the source program), source code to be called for
through COPY assembler instructions, or both.
- SYSPRINT
- A file containing the assembly listing
(if the LIST option is in effect).
- SYSTERM
- A file containing essentially a condensed form of SYSPRINT,
principally error flagged statements and their error messages
(only if the TERM option is in effect).
- SYSPUNCH
- A file containing object module output, usually for punching
(only if the DECK option is in effect).
- SYSLIN
- A file containing object module output usually for the linkage
editor
(only if the OBJECT option is in effect).
- SYSADATA
- A file containing associated data output
(only if the ADATA option is in effect).
The files listed above are described in the text following
Table 29.
The characteristics of these files, those set by the assembler and
those you can override, are shown in
Table 29.

Notes to Table 29:
- 1
- If you specify EXIT(PRTEXIT) and the user exit specifies the
logical record length, the logical record length returned is used,
unless the SYSPRINT data set has a variable-length record format in
which case the LRECL used is 4 bytes greater than the value returned
by the exit.
If EXIT(PRTEXIT) has not been specified or the user exit does not
specify a record length, the record length from the
FILEDEF command or file label
is used, if present. Otherwise, the record length
defaults to 133, or 137 if the record format is variable-length.
The minimum record length allowed for SYSPRINT is 121, and the
maximum allowed is 255.
If the record format is variable-length, the LRECL should be at least
125 or 137 depending on the LIST option.
- 2
- If you specify EXIT(TRMEXIT) and the user exit specifies the
logical record length, the logical record length returned is used.
If you do not specify
EXIT(TRMEXIT) or the user exit does not
specify a record length, the record length from the FILEDEF command or
file label is used, if present. If not present, the record length
defaults to the record length for SYSPRINT (if the LIST option is in
effect) or 133 otherwise.
The maximum record length allowed for SYSTERM is 255.
- 3
- Both fixed and variable formats are supported; the default is
fixed.
- 4
- If specified, the BLKSIZE must equal the LRECL, or be a multiple of
the LRECL.
If BLKSIZE is not specified, it is set to LRECL.
- 5
- The BLKSIZE on the FILEDEF command
or the file label must equal the
LRECL, or be a multiple of the LRECL.
- 6
- The blocksize must be equal to or a multiple of the record
length if the record format is fixed. If the record format is
variable, then the blocksize must be at least
4 bytes greater
than the record length.
- 7
- Set by the assembler to F (or FB) if necessary.
- 8
- Both fixed and variable formats are supported; the default
is variable.
If the FILEDEF command or file label
specifies machine or ASA control characters, the ASA
option is set or reset accordingly. If machine or ASA control
characters are not specified on the FILEDEF command or file label, the
record format is modified according to the ASA option.
- 9
- Set by the assembler to F (or FB) if necessary.
The record format is set to FA (or FBA) if the ASA option is specified,
or FM (or FBM) otherwise.
- 10
- You can specify B, S, or T, or any combination of these.
- 11
- The minimum record length allowed for ASMAOPT is 5. The maximum
record length allowed is 32756 if the record format is variable-length
or 32760 if the record format is fixed-length.
- 12
- If you specify the OBJECT option,the logical record length must
be 80. If you specify the GOFF option, the object module can be
generated with either fixed-length records of 80 bytes, or
variable-length records up to a BLKSIZE of 32720.
