A problem from beginner

You need to type something like:

fSave_data_old_format("Data_date", "0", "100")

into the command line.

I haven't look though the code in detail, but be aware that you need a certain datafolder which will define what "Data_date" is. And there need to be certain waves present.

Unless your two-dimensional data is something special, you don't need all that code to convert it to 1D, you just need Igor's Redimension command. For instance, if you make a 2D wave with 10 rows and 4 columns:
Make/N=(10,4) '2DWave'=p+10*q
This command fills the wave with values that are easily distinguished. I usually make a copy of my data before manipulating it, just so I don't destroy anything. You can do that from a dialog, using Data->Duplicate Waves menu item. That will generate a command something like this:
Duplicate '2DWave', '1DWave'
Note that '1DWave' is still two-dimensional. Now this command will convert it to a one-dimensional wave, while preserving all the data:
Redimension/N=40 '1DWave'
The key here is that N=40 is the same number of points as N=(10,4). In that case, Igor will rearrange the data (actually, the data are laid out in memory the same way, Igor just changes its interpretation of the arrangement).

Note that I have had the bad taste to use "liberal" names (the initial digit makes them liberal names) and had to enclose the wave names in single quotes.
