eval is having 2 arguments, so how to apply it to expression sequences?

eval(x=1,x=2,x=y);
Error, invalid input: 
    eval expects 1 or 2 arguments, but received 3

The usual approach is to convert an expression sequence to a list, apply eval, and then either use op, or [] at the end to convert it back to an expression sentence. Something like

eval([x=1,x=2],x=y)[];

                             y = 1, y = 2

or use quotting,

The NullSpace help page in online help uses {{...}} for sets instead of {...}. I didn't check other pages with help examples containing sets.

Just looked at the RowSpace (and ColumnSpace) online help pages. They contain [[...]] instead of [...].

There are a few useful commands in the MmaTranslator:-Mma. The help pages are rather confusing and don't seem to provide enough examples though. For example, take a look at the WriteString help page.

The calling sequence is WriteString(arguments) - and the Parameters section says that "arguments - Maple translation of the Mathematica command arguments", which assumes that the user knows the Mathematica arguments of that command.
