{{Trans|Forth}}
uBasic/4tH shares many features with Forth - like a stack. Parameters of functions and procedures are passed through this stack, so there is no difference between pushing the values on the stack ''or'' passing them as function parameters. Return values are passed by the stack as well, so if we push additional values ''before'' calling '''RETURN''' we can retrieve them using '''POP()'''.
<syntaxhighlight lang="qbasic">a = FUNC (_MulDiv (33, 11))
b = Pop()
Print "a * b = ";a, "a / b = ";b
Push 33, 11 : Proc _MulDiv
a = Pop() : b = Pop()
Print "a * b = ";a, "a / b = ";b
End
_MulDiv
Param (2)
Push a@ / b@
Return (a@ * b@)</syntaxhighlight>

=={{header|Binary Lambda Calculus}}==
In the lambda calculus, one can return a tuple, which when applied to a function f, applies f to all the tuple elements. For example, <A,B,C> is <code>\f.f A B C</code>. Alternatively, one can use continuation-passing-style (cps), in which the function f is not applied the tuple return value, but instead is passed as an extra initial argument, and then the function can return f applied to the multiple values.

=={{header|Wren}}==
In Wren, one would return multiple values from a function or method by using some sort of Sequence object, usually a List though a Map could be used if you needed ''named'' returns.
