Glenn,
In addition to several Z80 assemblers on SIMTEL20, such as Z80ASM and ZASM,
Wwhich I've had poor success with on my Osborn (Pprobably my own fault) there
is also a powerful debugging program called Z8E, on SIMTEL20, with which one
can assemble on the Z80 in a debugging environment. This is far more may be far more
useful to you in the process of learning assembler programming. A message
calling my attention to it follows:

Subject: Z8E - at last! a free Z80 debugger for CP/M
Z8E - a Z80 DEBUGGING MONITOR has been released to the public (it's
copyrighted but permission has been given for non-profit use).
Z8E is a professional quality interactive debugging tool designed
to speed the testing of Z80 assembly language programs. Origin-
ally written as a standalone monitor, Z8E was used in the deve-
lopement of the world's largest Touch-Tone Input/Voice Response
system. Now redone to run in a CP/M or TurboDOS environment Z8E
contains more features in less memory than any comparable soft-
ware product. Occupying less than 9K of memory, Z8E includes the
following among its many features:
- Full screen animated display of the program under
test while it is being executed by the Z80 (uses
cursor addressing, configurable by the user).
- Complete Z80 inline assembler, with labels, sym-
bols, expressions, and directives, using Zilog
mnemonics
- Interactive disassembly with labels and symbols
to console or disk allows the user to specify
output formats and add comments
- Fully traced program execution including a full
screen single step command that instructs Z8E to
disassemble code and to move the cursor to the
next instruction to execute
- Up to 16 user settable breakpoints with optional
pass counts
- True symbolic debugging using the input from
multiple Microsoft MACRO-80 .PRN and LINK-80
.SYM files and Z80ASM .LST and SLRNK and Z80ASM
.SYM files from SLR Systems.
- Dynamic relocation of Z8E at load time to the top
of user memory regardless of size. No user
configuration of any kind is required.
The files are available as:
Filename Type Bytes CRC
Directory MICRO:<CPM.DEBUG>
Z8E.LBR.1 BINARY 104704 1D4CH
...which contains the .COM, DOC, and SYM for patching cursor control.
Z8E.MQC.1 BINARY 112512 4925H
...the source code, for those who wonder how it works. This was not
put into the LBR because I felt not everyone would need the source and
the LBR is already VERY big.
If you are unable to access Simtel-20 because of network restrictions
please remember that MOST of the new files announced to Info-Cpm are
also available on my RCPM Royal Oak (MI) which may be accessed at 300
bps using the 103a modem mode or 1200 bps using either the 212a or
Vadic 3400 modes. The telephone number is (313) 759-6569.
