Try this:
\define makelink(text,prefix,link)
[[$text$|$prefix$$link$]]
\end
<$macrocall $name="makelink" text="LinkText" prefix="prefix" link={{!!code}}
/>
Some feedback on your attempts:
\define getfoo(title=<<current>>)

* <<current>> is not a pre-defined variable, so it has no assigned value.
The TWCore sets <<currentTiddler>> to title of the current tiddler.
Perhaps that is the variable you were thinking of
* The syntax for defaults for macro params is paramname:value (not
paramname=value) and only accepts literal values surrounded by delimiters
using single-quotes ('foo'), double-quotes ("foo"), doubled square brackets
([[foo]]), or tripled double quotes ("""foo"""). You can't use a reference
to another variable (or a transcluded field value).
* You declare the 'title' param, but never *use* it in the macro
definition, so it's not clear what you intend to use it for.
test <<getfoo>>

* invoking <<getfoo>> here returns "{{foo1!!code}}", which is then rendered
as a transclusion, displaying the value in the specified field
[[{{foo1!!code}}]]

* the macro returns "{{foo1!!code}}" and is not recursively re-parsed to
retrieve the value contained in that field. Thus, you are linking to a
tiddler whose title is literally "{{foo1!!code}}".. which, is very likely
NOT what you intended.
<$link to={{foo1!!code}}>Link Text</$link>

generate/render output. They do not return values.
Hope this helps,
