The T-RDLBL command reads a tape label, whether it is at the beginning of a tape, or at the beginning of a file (i.e., after an End-Of-File mark). Using the T-RDLBL command when a labelled tape is mounted sets the block size to the record length specified in the label.

Hexadecimal number of the tape cartridge. |
T-RDLBL reads the tape and displays on the screen the reel number, block size, time, and date from when the tape was written, and a header text. T-RDLBL, like T-READ, if not at a label, will rewind the tape.
If you use T-RDLBL on a tape that is one of a set of tapes, the number of the tape is included with the label. At the end of the tape, you are prompted to load the next tape in sequence. If you supply a tape number, it overwrites the number read from tape. Thus, you could type T-RDLBL 3 for any tape so that when the NEXT-TAPE-REQUIRED message appears, you must mount tape 4.
