Create formatted datasets that can be read by Read_formatted. The first line contains:
[data block name] [data_block_type] [number_items] [format]
The data block name must be less or equal to 25 characters and not contain spaces. The data block type can be T, C, R, or I. If the type is T then the number of items is the number of lines of text and the format is the number of characters on a line,otherwise it really is the number of items and the FORTRAN style format. For example p1 i 5 (5i2) or p2 t 5 72 are both O.K. specifying integer and text data, respectively. Subsequent lines contain the information, as specified in the format statement or the line count.
