I agree with you, Jens. Everything I suggest below can wait until after RELATE and GCP. None of that is required for data entry. Jamie

Jamie can you extend the suggestion with a series of "let" examples, that clarifies the extend. My consideration is not so much whether to add something simple, but I think we should be careful not to constantly postpone highly desired functionality such as relate or GCP functionality with logging.

Additional functionality for Manager calculations:
- It will be very useful to have some more calculation possibilities as we had in .chk files. In order of priority:
- minimally, the following via the menu/drop down approach that exists:
- add/subtract an integer variable or constant to/from a date field to yield another date field
- result field = fn(source field[, source field b]) (where fn is a function as for the LET statement in .chk)
- substr for string combinations
- ideally, the ability to enter a text string that defines a calculation based on other fields (equivalent to LET statement in .chk). We should keep the functions to a limited set of those available for LET. I'm not sure what is most useful. Doing some calculation during entry is useful, as this allows for additional validity checking
- the ability to reference value labels in another project (equivalent of COMMENT LEGAL USE abc.rec)
