Are the numeric values on single record or is the linewrap a figment of the display? Is there some auxiliary data that informs the number of elements in each section?
How do you know which line(s) to modify and which values within the lines to change (and to what)?
Basically, the thing with sequential files is that they're, well, "sequential". Which means basically, start a loop, read a line, process it, write the new line, rinse, and repeat until feof().

So read the numbers in an array
numberArray=myreadingfunction(...);
then filter those that you don't want Lets say your condition to delete a number is if it is larger than 500 but smaller than 550.
mask= (numberArray>500 & numberArray<550);
now remove them from number Array:
numberArray=numberArray(~mask);
Now write this to a file.
We don't know what is your criteria to remove a number so that part you would know.
