Par2: Returning mulitple values from a function 1999-02-05 -- Robert Fred Meyer As mentioned by the other two, passing by address is the best way to get
multiple values returned. But if you really want multiple values returned
without passing by address then there is a way. Make a project for the
following program and run it.
---------------------------------------------------------------------------
program
map
MultiReturn(ulong xV1, ulong xV2, ulong xV3),string
end ! map
MultiReturns group
V1 ulong
V2 ulong
V3 ulong
end ! group
code
MultiReturns = MultiReturn(3,5,7)
message('V1: ' & MultiReturns.V1 & |
'|V2: ' & MultiReturns.V2 & |
'|V3: ' & MultiReturns.V3 )
MultiReturn procedure(ulong xV1, ulong xV2, ulong xV3)
MR group(MultiReturns)
end ! group
code
MR.V1 = xV1 * xV1
MR.V2 = xV2 * xV2
MR.V3 = xV3 * xV3
return(MR)

Jean-Marc comments:
Put simply, you just declare a function to return a string and you return a
group.
You then reads the values from the group.
