Now that I have enabled the x64 compiler I have managed to start compiling the program. As Steve mentioned in the previous discussion I have had to make all integer variables relating to handles integer(HANDLE) type when using Win32 API calls, also the lparam term of the SendMessage function needs casting as int(xxx,UINT_PTR) kind. There area coupleother issues that I have encountered so farfor which I would be grateful for any advice.
1. the statement !DEC$ OBJCOMMENT LIB:F90SQL.LIB produces a sytax error, "found IDENTIFIER 'F90SQL' when expecting one of:
2. What do you use toreplicate the LOWORD(mesg%lparam) or HIWORD(mesg%lparam) macros, where mesg is the defined as a T_MSG data type. Currently I get a warning that data type of argument does not match the definition [laparm].
Thanks for reading

F90SQL.LIB needs to be in quotes- it does need to be a character constant.As it is, unquoted, the compiler thinks it's a symbol. I'm not sure how this compiled previously. Try a space between the ":" and the character string but I think it's the lack of quotes that is the problem.
F90SQL is a 32bit library - you are right, you will get a link error if you try to use that with a x64 application. I am not sure, but I have not seen a 64bit version of that library. If you find one, please let all of us know.
HIWORD and LOWORD require 32bit integers as arguments. You can try:
HIWORD( INT(mesg%lparam,4) ) to convert the 64bit integer to a 32bit integer. However, you are truncating the upper 2 words doing this. Is the data still stored in the lower 2 words of lparam inyour 64bit code? If so this should work.
LOWORD( INT(mesg%lparam,4) ) should work fine, since I assume the data in the lower word is still the same in the 64bit case.
