* purpose:  Data upload functions

*           This module contains all the functions required to upload

*           data from the handheld calculators and insert the data

*           into the data base as well as functions and a menu to load

*           and unload specific data into the data base

*

* functions

*       upload                  - Get Leg to upload

*       ins_data                - Insert time info into data base

*       supload                 - Extended upload functions menu

*       tupload                 - Read in text team information

*       t_parse_number          - Parse a number from a CSV line of team text

*       t_parse_text            - Parse string from a CSV line of team text

*       p_del                   - Test for a delimiter.

*       tdnload                 - Generate team name file

*       dnload                  - Generate leg timing file

*       getfname                - Get a filename from the user

*           May 1990    Margherita Veroni

*                               The functions to upload data have been modified

*                               to allow leg start times to also be uploaded for

*                               any leg. Data being uploaded which contain errors

*                               are written to an error file

*

*   00.0    1-Apr-94    DDP     Changed tdnload() to produce a comma seperated

*                               file. This allows external users to see the

*                               field delimters better than tabs

*

*   00.0    27/01/95    DDP     Tidies up the program and formatted the file
