This describes the SIMDET V4.01 free format data cards.
The initialized default values are given in parentheses. Note that file names should be enclosed in single quotes, start with a point and end with a blank. The length of all file names is restricted to 80 characters.
Certain obvious logical restrictions apply to the proper combination of options. For example, option 'PYTH 1' does not allow for event reading from an external file.
