The following records are used in the rainfall files: 20, 21, 22, 23 and 60-63. The record 60 has been added to specify the output interval and storm duration to be run in conjunction with this rainfall data.  Records 61 and 62 have been added to allow parameters for the new runoff equation and record 63 for the new unit hydrograph method (ReFH).

Records 60-63 are optional but where used they must be put at the head of the file. The file then contains 1 record 20, 1 record 21 and then a record 22 for each profile. The file finishes with a series of record 23’s specifying the rainfall.
