Source
Standard IO for the loader and disassembler, Ldo and
Das, are included by the assembler .REXT directive in
Ldo.a, and Das.a, for the system specified by
k=# on the AAma command line. See the two source
files for the meaning of negative options, k=-#.
In debugging mode, the loader overlays debugging and disassembly
functions by reading in two object files, Deb.ab and
Dis.ab, assembled from Deb.a and Dis.a.
For the Minimum this code may be in ROM instead. A few IO functions from
IOst.a are assembled into Deb.ab by a .REXT
directive in Deb.a.
Source for disassembling Apple IIGS W65816 code is not included in this
distribution.
The symbolic debugger function of Ldo fails under NeXTstep 3.3
on the Previous emulator with new builds or cross builds using the
source below. The other functions work as expected. Until the reason
is tracked down, the working snapshot version of the Ldo
executable provided in ../bin/
should be used to run the debugger. It works with command line windows
having 40 rows and 80 columns. The NeXT debugger screen size is set in
Deb.a by the following lines:
@15
scsize: .BYTE 40,80,0,0,0,0 ;screen size.
