#### 9.50.6 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.
