Good Lord!...

Revision of patterns, also rearranged to prioritize logical and dot operators:

m.loTokenizer.AddTokenPattern("\.([aA][nN][dD]|[oO][rR]|[nN][oO][tT])\.", "O")
m.loTokenizer.AddTokenPattern("([mM]\s*(\.|->)\s*)?[a-zA-Z][a-zA-Z0-9_]*\s*(\(|\[)", "F")
m.loTokenizer.AddTokenPattern("([mM]\s*(\.|->)\s*)?[a-zA-Z_][a-zA-Z0-9_]*", "V")
m.loTokenizer.AddTokenPattern("(\.|->)\s*[a-zA-Z_][a-zA-Z0-9_]*\s*(\(|\[)", "M")
m.loTokenizer.AddTokenPattern("(\.|->)\s*[a-zA-Z_][a-zA-Z0-9_]*", "P")
m.loTokenizer.AddTokenPattern("(\+|-)?(\.\d+|\d+(\.\d+)?)((e|E)(\+|-)?\d+)*", "N")
m.loTokenizer.AddTokenPattern('("[^"]*"|' + "'[^']*'|\[[^\[]*\])", "C")
m.loTokenizer.AddTokenPattern("{\^\d{1,4}-\d{1,2}-\d{1,2}}", "D")
m.loTokenizer.AddTokenPattern("{\^\d{1,4}-\d{1,2}-\d{1,2}\s+\d{1,2}:\d{1,2}(:\d{1,2})?(\s+?([aA]|[pP])[mM]?)?}", "T")
m.loTokenizer.AddTokenPattern("\.([tT]|[fF])\.", "L")
m.loTokenizer.AddTokenPattern("\.[nN][uU][lL]{2}\.", "U")
m.loTokenizer.AddTokenPattern("(==|!=|<=|>=|<>|!|=|>|<|\+|-|\*|\/|%|,|\)|\(|\$|[aA][nN][dD]|[oO][rR]|[nN][oO][tT])", "O")

Thank you for your very close look into this...
