Can't really say much more than that due to the vagueness of the question.
Can you give an example string (make it a short one, less than 30 characters but containing 3-4 data items that need assigning), and structure, and what should be assigned to what, and I'll consider having a go at presenting an example of how I might do it.
the string read from file will be like ACM.IODATA.DI.DI1WORD3.T4 and it has to be converted to structure variable.
