Hi All,
I have another question about formatted input. Suppose I am reading a
text file, and that I want it to be something like this

word11 = num11, word12 = num12, word13 = num13 etc...
word21 = num21, word22 = num12, word23 = num23 etc...

where wordx1 belongs to a certain dictionary of words, say dic1, while
wordx2 belongs to dic2, the numbers within some range and so on. I was
wondering if there is something in the standard library I may use to
check whether the file I am reading has a correct syntax according to
my rules/dictionaries instead of implementing my own routine that
would look like
for each line
  put words into a list
  check condition for each word
