> I know that UDT passes by reference Interesting. The UV documentation for the CALL statement says: "All scalar and matrix variables are passed to subroutines by reference. If you want to pass variables by value, enclose them in parentheses."
Enclosing a matrix in parentheses apparently does not actually work. (UV10.0.7 aix) Vlisting the difference between a scalar and a vector (1D matrix) variable surrounded by parentheses shows in the first example, using a scalar variable, passes by value using a new internal variable _T0000. In the second example, surrounding a vector in parentheses does nothing and the vector is passed by reference, the same as if there were no parentheses. --- 1 00005: CALL P2((A), MAT X) 00005 00022 : 0F8 move A => _T0000 00005 00028 : 01E call "P2" _T0000 X --- 2 00005: CALL P2((X(100)), MAT X) 00005 00018 : 01E call "P2" X(100(1(X Seems like a bug in the documentation.
