z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

-ax Instructs the assembler to produce the DSECT Cross Reference
topic of the assembler listing. This is equivalent to specifying:
--DXREF.
=file Specifies the file name of the listing output. If you do not specify a
file name, the output goes to stdout.
You may combine these options; for example, use -ams for an assembly
listing with expanded macro and symbol output. The =file option, if used,
must be specified last.
-g Instructs the assembler to collect debug information. By default, the debug
information is produced in DWARF Version 3 format (or --gdwarf3).
--[no]gadata[=file]
Instructs the assembler to collect associated data and write it to the
associated data file. You can optionally specify the name of the output
debug file. The specified name cannot be a PDS or z/OS UNIX file system
directory name. If you do not specify a file name, the default name is
created as follows:
v If you are compiling a data set, the as command uses the source file
name to form the name of the output data set. The high-level qualifier is
replaced with the user ID under which the as command is running, and
.ADATA is appended as the low-level qualifier. For example, if TS12345 is
compiling TSMYID.MYSOURCE(src) with this option, the produced debug file
name will be TS12345.MYSOURCE.ADATA(src).
v If you are compiling a z/OS UNIX file, the as command stores the debug
information in a file that has the name of the source file with an .ad
extension. For example, if you are compiling src.a with this option, the
compiler will create a debug file named src.ad.
-moption
HLASM keyword options are specified using the following syntax:
-m[=[=][:[=]]...]
where is an option name, is a suboption name, and
is the suboption value.
Keyword options with no parameters represent switches that may be either
on or off. The keyword by itself turns the switch on, and the keyword
preceded by the letters NO turns the switch off. For example, -mLIST tells
the HLASM assembler to produce a listing and -mNOLIST tells the HLASM
assembler not to produce a listing. If an option that represents a switch is
set more than once, the HLASM assembler uses the last setting.
Keyword option and parameter names may appear in mixed case letters in
the invocation command.
-I PDS Instructs HLASM to look for assembler macro invocation in the specified
location. The PDS data set specified must be fully qualified. The specified
locations are then prepended to a default set of macro libraries. The as
command assumes a default set of macro libraries that is compatible with
the defaults for the C/C++ compilers. The default data sets used are: -I
CEE.SCEEMAC, -I SYS1.MACLIB, and -I SYS1.MODGEN. The default
data sets can be changed via the environment variable _AS_MACLIB, for
example:
export _AS_MACLIB="FIRST.PDS:SECOND.PDS"
