MTBLKTOOSM, Magtape BLOCK_SIZE is less than xxxx bytes
Run Time Error: This indicates that an OPEN command specified a BLOCK_SIZE device parameter that is smaller than this type of tape can handle.
Action: Review the program to ensure that block sizes do not fall below host driver limitations. For example, the industry standard for 9-track tapes is to treat blocks smaller than 14 bytes as noise in an inter-record gap.
