Lcd's don't normally take decimal #s. If you want it to go there and since you are talking about an Instruction. First you convert your decimal to a binary. 40 converts to %0010_1000. But in order for the LCD to take it as an instruction to goto row #2 first space, you need to add a 1 to the beginning of that binary number (like this %1010_1000). When you are sending instructions be sure RS = 0 and RW = 0 (or RW is grounded)

After you have sent the cursor to the location you desire, then follow it with RS = 1 and RW = 0 and the LCD is ready to print data at the cursors new poition.

If you need to just display data asap, a Serial LCD is the easiest LCD to work with, but I think Parallel LCD's are an excellent precursor to other chips that interface to a SX.
