hi, everyone,

I am new to VEE and came up with one simple problem.
I have a set of data saved in .txt file as shown in the following.

342.4,-17.618
343.4,-17.613
344.4,-17.616
345.4,-17.606
346.4,-17.601
347.4,-17.599
348.4,-17.602
349.4,-17.598
350.4,-17.588
351.4,-17.58

I want to generate one new set of data, which is also two columns, but the
starting and ending row would not be 342.4 and 351.4, but the one I could
assign. 
e.g., if I assign 345.4 and 349.4, the data set would look like:

345.4,-17.606
346.4,-17.601
347.4,-17.599
348.4,-17.602
349.4,-17.598

Is there any find or search function in the I/O From file or I need to
load this data to array and do the process? Any hints or suggestions?

Please forgive me for my naive question. Your help would be greatly appreciated!
