9.49.6 VAX Operands

The immediate character is ‘ $ ’ for Unix compatibility, not ‘ # ’ as DEC writes it.

The indirect character is ‘ * ’ for Unix compatibility, not ‘ @ ’ as DEC writes it.

The displacement sizing character is ‘ ` ’ (an accent grave) for Unix compatibility, not ‘ ^ ’ as DEC writes it. The letter preceding ‘ ` ’ may have either case. ‘ G ’ is not understood, but all other letters (b i l s w ) are understood.

Register names understood are r0 r1 r2 ... r15 ap fp sp pc . Upper and lower case letters are equivalent.

For instance

     tstb *w`$4(r5)

Any expression is permitted in an operand. Operands are comma separated.
