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

System Variables

The following system variable symbols are defined somewhat differently by the Tachyon assemblers than by the IBM High Level Assembler.

&SYSADATA_DSN: &SYSADATA_DSN is set to the Associated Data file name if the ADATA option is set.
&SYSADATA_MEMBER: &SYSADATA_MEMBER is set to the upper-cased part of the Associated Data file name between the last directory separator and the first period.
&SYSASM: &SYSASM is set to 'TACHYON 390 CROSS ASSEMBLER' or 'TACHYON Z/ASSEMBLER'.
&SYSCLOCK: The resolution of &SYSCLOCK is usually not to the microsecond level due to the limited resolution of the time-of-day information available from most operating systems.
&SYSIN_DSN: &SYSIN_DSN is set to the path name of the source file or to '(STDIN)' if the source is being read from stdin.
&SYSIN_MEMBER: &SYSIN_MEMBER is set to the upper-cased part of the source file name between the last directory separator and the first period. It is set to a zero-length string if the source is being read from stdin.
&SYSJOB: &SYSJOB is set from the workstation’s node name. If not available, &SYSJOB is set to 'X390'.
&SYSLIB_DSN: &SYSLIB_DSN is set to the path name of the file containing the macro definition.
&SYSLIB_MEMBER: &SYSLIB_MEMBER is set to the upper-cased macro name if it was implicity defined. If the macro was explicitly defined, &SYSLIB_MEMBER is set to the value of &SYSIN_MEMBER at the time of the definition.
&SYSLIN_DSN: &SYSLIN_DSN is set to the Object File name if the OBJECT(OMF), OBJECT(XOBJ), OBJECT(GOFF) or OBJECT(ELF) option is set.
&SYSLIN_MEMBER: &SYSLIN_MEMBER is set to the upper-cased part of the Object File name between the last directory separator and the first period.
&SYSPRINT_DSN: &SYSPRINT_DSN is set to the Assembly Listing file name if the LIST option is set.
&SYSPRINT_MEMBER: &SYSPRINT_MEMBER is set to the upper-cased part of the Assembly Listing file name between the last directory separator and the first period.
&SYSPUNCH_DSN: &SYSPUNCH_DSN is set to the Punch Deck file name if the OBJECT(DECK) option is set.
&SYSPUNCH_MEMBER: &SYSPUNCH_MEMBER is set to the upper-cased part of the Punch Deck file name between the last directory separator and the first period.
&SYSSTEP: &SYSSTEP is set to the current user ID. If not available, &SYSSTEP is set to '(NOSTEP)'.
&SYSTEM_ID: &SYSTEM_ID is set from the SYSTEMID option value or its default.
&SYSTERM_DSN: &SYSTERM_DSN is set to the Assembly Messages file name if the TERM option is set. If the SYSTERM(1) option was specified, &SYSTERM_DSN is set to '(STDOUT)' and if SYSTERM(2) was specified, &SYSTERM_DSN is set to '(STDERR)'.
&SYSTERM_MEMBER: &SYSTERM_MEMBER is set to the upper-cased part of the Assembly Messages file name between the last directory separator and the first period.
