ff_tbl

char ff_tbl

Initial value:

= {"string", "decimal_int", "hex_int", "float", "double",
         "currency", "yyyymmdd", "hhmmss", "apr", ""}

ff_tbl - a table of field format strings used in the Form description file to identify field data types the index of the field format in this table corresponds to the FieldFormat enum values, e.g. ff_tbl[FF_STRING] = "string", ff_tbl[F_DECIMAL_INT] = "decimal_int", etc. a table of field format strings used in the Form description file to identify field data types, e.g. "string", "decimal_int", "hex_int", etc. The index of the field format in this table corresponds to the FieldFormat enum values, e.g. ff_tbl[FF_STRING] = "string", ff_tbl[FF_DECIMAL_INT] = "decimal_int", etc. This table is used for parsing the form description file and determining the field formats for each field in the form.
