Datalogger Distress -> Solved

Hi. Well, I'll bite. I always seem to have trouble with the datalogger, and it never seems to be just right. However, I can usually fix any problems with enough contemplation and an Ah-Ha moment. Not this time: I can't seem to get it to read the file. I'm sure that the preparation is working since the light on the USB thumb drive blinks at that time, but nothing happens at the first read (line 100). I've reproduced it here:
Anyway, the test program works, so I'm fairly certain it's not a hardware error. I'm using a BS2px. You can ignore the code at the begining: thats just so that I can choose the right action. When I run it, it goes through everything until it reaches the SERIN on line 101. It then times out and goes to the No_Data2 method. Even with the huge timeout counter I gave it.
Any suggestions?

Any of you long time programmers know that euphoric sense that you get when you solve a problem that just didn't go away? Well, that's what I feel like. Yay!!!
This issue has been a thorn in my side for months. I'd periodically get the nerve to pull out the platform and do some more testing, but it was always the same thing. Near the end, I was just repeating the same things over and over, and it was no wonder that they didn't work.
Today, I took my BOE and laptop to the EE support lab, where electronics are piled high on every flat surface, and was looking for some inspiration. Guess I'll be going back quite often, since it worked.
What was the problem? Well, it was one or two things (I was just messing around, without a real test plan): Either a) I cannot use a variable in the file name, or possibly I didn't do it right, or b) the DEC formatter kept the SERIN command waiting for a byte that never came.
Anyway, I'm just happy (no, too weak a word: overjoyed, jubilant, ecastic would all be more accurate) that I've got this working. I've moved past my Achilles Heel, and will soon have a roving robot.
Cheers mate, and Best to you and Yours!
This is why some folks on here tell people to read the manuals....sure, you might not get the answer you want right away, but by figuring out yourself, you'll remember it much longer!
Now the trick is to not do too much at once....so you can remember the effective solution!
Can you go back to the non-working program and try either of the suspect solutions and see which one was the fix!?

Anyway, ran into another snag. For some reason the program stops at the following SEROUT command:
·I can't think why. There's nothing really for the BS2 to wait for, except for possibly the flow control. Any guesses on how that mechanism works? Or possibly any other suggestions? The code is essentially the same as the first post.
