I have a line in a text file in wich I want to replace some text.
I read a line of the file, check if it is the line to be modified. If
it is not than I go to the next line and so on till the end of the
file.
If it is the line to be modified than I replace the line part with the
correct text and want to write the corrected line back to the file.
So far looks good, but when I look in the corrected file in stead of
good characters I only see ascii squares.
(It is not the whole story but a short version of the actions)
Can someone help me with this please?
