I am working on a project, which takes input data from .dat file which is 3000 charaters/row and more than 30000 rows per file.
- There is not delimiter in .dat file. Each field is of fixed number of charaters and fixed poisition in row.
- If there is no data for field then filled with blank spaces.
- Field's data may be alphanumaric
Which one is fastest way to import data? and how
1. Into predefined 'TYPE' structure?
2. Into CLASS?
3. Into predefined charater 'ARRAY'?
