Insert a Record into a Data Set (WRTI)Source:WRTIObject:oJ318 I 11 r 15 7 23 7D D II II31D Bits:8 Not used, always zero.9 0= Overlap mode (0 specified).1 = Nonoverlap mode (N specified).10 Not used, always zero.11 0 = I/O buffer is not blanked.1 = I/O buffer is blanked at the start of the operation (B is specified)if a format is specified.D Data set number: The number (hex 1-F) of the data set to be accessed.II Format number: The number (hex 01-FE) of the format to use. If no formatis specified, this will be hex FF.II Record to access: Always the current record (hex 08).This instruction writes the current logical record to the physical buffer, into thecurrent record position. The record that was in the current record position, and allrecords beyond the inserted record, are moved down one position until EOD or adeleted record is encountered. If the record is inserted as the last record in the dataset, this instruction acts as a write instruction (op code 30).Note: Two physical buffers and one logical buffer must be available for thisinstruction.186
