It works here.  And PowerBasic does not have an error that says 'does
not work'.
In the example you gave, t is a 15-byte fixed-length string, so why
in the world would you tell the SUB it is a user-defined type?  The SUB
statement is where you tell the subroutine what kind of variable you
will pass it.  The error 481 you got is telling you that you are trying
to pass a different kind of variable than you said you would.
You gave two variations, A and B.  in B, you tell the sub to expect a
variable-length string but try to pass it a fixed-length string.  That
causes an error 481/parameter mismatch.  In A, you convert the
fixed-length string to a variable-length string, call the sub, and
convert the value it returns back to fixed length.  That, naturally,
works.  (And if you want to use that subroutine for strings with a
length of other than 15 bytes, might be a better way to do it anyway).
BTW, your example has two different variables called t.  One is of a
user-defined type in the main level, the other is a variable-length
string in the subroutine.  Don't confuse them.
