ASSEl'1BLE 4. You cannot assemble programs using DOS macros from the DOS/VS source statement libraries under eMS/DOS. You should use the SSERV, ESERV, and MACLIB commands to create eMS MA:LIBs to contain DOS macros for assembly under CMS/DOS. See the for examples.
5. You do not need to make any logical assignments for input or output
files when you use the assembler under eMS/DOS. File definitions
are assigned bV default under eMS, as described in Usage Note 1.

specifies the system or programmer logical unit to be assigned
to a particular physical device. SYSOOO through SYS241 are
valid programmer logical units in eMS/DOS; they may be
assigned to any valid device. The system logical units you may assign, and the devices to which they may be assigned,
are: SYSRDR SYSIN SYSPCH SYSLST SYSLOG SYSOUT SYSSLB SYSRLB SYSCLB SYSCAT Reader,disk,tape

blocked) PUNCH is the spooled punch. PRINTER is the spooled printer. TERMINAL is your terminal (terminal 1/0 must not be blocked). TAP[n] is a magnetic tape. n is the symbolic number of the tape
drive. It is either 1, 2, 3, or 4, representing virtual
addresses 181, 182, 183, and 184, respectively. If n is
omitted, TAPl is assumed.
mode specifies the one-character mode letter
assigned to the logical unit (SYSxxx). accessed when the ASSGN command is issued.
