Read

This option can be used to read in a file containing datum line definitions that has previously been saved.

All datum lines must have a unique acronym. When the file is read the user has the choice to:

1. Delete any existing datum line definitions before the file is read.
2. If a datum line in the file being read has the same acronym as an existing datum line then the existing definition will be overwritten.
3. If a datum line in the file being read has the same acronym as an existing datum line then the new definition in the file will be ignored.
   
   

The preference option

this*datum_file : C:\datum\this001.dtm

can also be used to define a default file containing datum line definitions that is read automatically when T/HIS starts (see Appendix H for more details)
