I am Writing a program which converts latin text to original Language script. this where i have gone so far

' Mapping for Ascii to Unicode

The underlined part produces this error - "Expression Does Not Produce a Value", any help would be highly appriciated. And Thanks in advance

Array.Reverse is a procedure without a return type.
To fill your arrays you should reverse it and then copy into the array
just like

Private mapAsciiToUnicode() As String = {"h" >= "1920", "S" >= "1921", "n" >= "1922", "r" >= "1923", "b" >= "1924", "L" >= "1925", "k" >= "1926", "a" >= "1927", "v" >= "1928", "m" >= "1929", "f" >= "1930", "d" >= "1931", "t" >= "1932", "l" >= "1933", "g" >= "1934", "N" >= "1935", "s" >= "1936", "D" >= "1937", "z" >= "1938", "T" >= "1939", "y" >= "1940", "p" >= "1941", "j" >= "1942", "C" >= "1943", "X" >= "1944", "H" >= "1945", "K" >= "1946", "J" >= "1947", "R" >= "1948", "x" >= "1949", "B" >= "1950", "F" >= "1951", "Y" >= "1952", "Z" >= "1953", "A" >= "1954", "G" >= "1955", "q" >= "1956", "V" >= "1957", "w" >= "1958", "W" >= "1959", "i" >= "1960", "I" >= "1961", "u" >= "1962", "U" >= "1963", "e" >= "1964", "E" >= "1965", "o" >= "1966", "O" >= "1967", "c" >= "1968", "," >= "1548", ";" >= "1563", "?" >= "1567", ")" >= "0041", "(" >= "0040", "Q" >= "65010)"}
