An input record may contain several items. The general rule is that each sequence of characters that does not contain a delimiter is an entity. Delimiters in this context are: 1) the blank or space character ' ', 2) the comma ',' and 3) the equal sign '='.
It is assumed throughout that only characters of the Fortran character set are used.
DO NOT USE TABS IN THE INPUT FILE! The program may not see them as delimiters and the effects are hard to predict!
