SBTCVM's assembler has been with it for a long time. Since the prototype era actually. Gen 2's ground-up rebuild of the VM also brings a similar treatment to good old SBTCVM tasm.
Syntax checks:
no less than 2 syntax check passes and 1 validation pass before writing to a trom file, along with a new trom format, ensure problems with corrupt roms are unheard of in Gen 2. saving coders time and energy.
simple numeric data tweaks:
first, decimal support has been added:
setreg1;10x32
setreg1;10x-12
second, ternary support has been overhauled:
two representations are supported:
+0-
p0n
Also, ternary values can be any arbitrary length from 1 to 9 trits.
Unified namespace:
the goto reference label, iobus address macro, and other namespaces accessed via '>' have been merged into a singular namespace, with custom variable support:
the v> prefix keyword supports all the numeric representations supported by most keywords:
v>myvar;10x1
They can even point to namespace entries to duplicate their value.
v>myvar2;>myvar
normal keywords can do this too:
setreg1;>myvar
dual data ahoy:
Gen 2's new dual-packing concepts and the mirrored data/instruction size have been complimented by a new raw instruction:
raw;10x56,pn00pn'
They, of course, can be mixed numeric syntaxes.
Overall:
This rock solid, modular, base of features will prove to be very useful in the coming months, as the Gen 2 instruction set and CPU development enter full swing.
