0020 DESCRIPTION
0021 -----------
0022 Function is used to get field data from UBF buffer. 'p_ub' is pointer to UBF buffer, 'bfldid' is field id, 'occ' is field occurrence at buffer, which needs to be read. 'buf' is buffer where to output the data, data is automatically converted to *BFDL_STRING*. It is assumed that space in 'buf' is large enougth to store the value.
0023
0024 This is macro function and it invokes *CBget(3)* with field type *BFLD_STRING* and length 0.
