This is a fairly standard "problem."  However, I think your definition is
under-determined.  Is 'base' the current base of the number, or the base
to which it is to be converted?

Might I suggest:

function convert(inbase, outbase : integer; input_num : string) : string;

I would be more impressed with code that does this directly, rather
than converting to base 10 (or 2, or 16, or...) first.

For example, convert 10110101 base 4 to x base 7.

x:= convert (4, 7, "10110101");
