Tachyon 390 Cross Assembler and Tachyon z/Assembler User's Guide

Changes in this Release

Version 3.1 of the Tachyon 390 Cross Assembler and Tachyon z/Assembler adds support for IBM High Level Assembler release 6 and more, including:

The default ADATALEVEL option value is now 6, indicating that the ADATA records are to be produced in HLASM release 6 format.
The OPTABLE abbreviations for ZS3 and 370 have been changed. Previously they were S and 3 respectively. Now they are 3 and 7.
WORKFILE is now a synonym for SIZE(0) and NOWORKFILE is now a synonym for SIZE(MAX).
The FLAG(ALIGN) option now causes a new informational message TXA600I to be issued instead of the warning message TXA500W when the instruction does not require operand alignment.
The new FLAG(ALIGNWARN) option causes the assembler to issue message TXA500W as FLAG(ALIGN) did in prior releases.
The FLAG(LINT) option sets FLAG(ALIGNWARN) instead of FLAG(ALIGN).
The tas option -march=z10-ec has been changed to -march=z10 for compatibility with the GNU assembler.
Statistics for messages suppressed by the SUPPRESS and SUPRWARN options are reported in the ADATA type X'0090' record and the listing.

:MAC and :ASM may be specified at the end of the operation name to indicate that the macro or non-macro version of an operation is to be used.
The OPTABLE operand of the ACONTROL statement is supported.
QY and SY storage definitions are supported by the Tachyon z/Assembler. They are not supported by the Tachyon 390 Cross Assembler or the Tachyon Legacy Assembler. QY storage definitions require the OBJECT(GOFF) option.
ISDEC, ISBIN, ISHEX, ISSYM are SETA, not SETB functions for compatibility with HLASM APAR PK27577.
&SYSM_HSEV and &SYSM_SEV are 3-character symbols, not arithmetic symbols.
If the FLAG(NOHLASM) option is in effect, the following language extensions are supported:
- The maximum SETC symbol length is 50,000 characters.
- The maximum DS/DXD length is same as maximum EQU length.

The abbreviations for the OPTABLE option have changed. 3 is now the abbreviation for ZS3 instead of 370. 7 is now the abbreviation for 370. S is no longer valid as the abbreviation for ZS3.
The FLAG(ALIGN) option now causes an informational message to be issued instead of a warning message when the instruction does not require operand alignment. The prior FLAG(ALIGN) option behavior is available with the new FLAG(ALIGNWARN) option.
The colon character has been added to the Standard Character Set and 3A=7A has been added to the unmodifyable translation table.
