Transfer Block Length and Transfer Block Count Modification command

You can modify the transfer block length and the transfer block count for a file transfer that is queued in the Send Queue.

Transfer Block Count and Transfer Block Length Modification Command

F  Job name of Send program,TBC,F=fileid[,H=hostname]{[,B=99999][,C=99]}

F  Job name of Send program,TBC,NO=99999..999{[,B=99999][,C=99]}

F=fileid

This parameter defines the file ID for the file transfer in the Send Queue whose definition values you want to modify. (Mandatory)

To modify the definition values for instant transfer, specify "_INSTANT_TRANSFER_" for the file ID.

H=hostname

This parameter defines the name of the host on the receiving side for the file transfer in the Send Queue whose definition values you want to modify. (Optional)

Defaulting this parameter modifies the transfer block count and the transfer block length of every file transfer for the relevant file ID.

NO=99999..999

This parameter defines the Send SEQ No. for the file transfer in the Send Queue whose definition values you want to modify. (Mandatory)

B=99999

This parameter defines the transfer block length for the Send processing. (Optional)

Specify '0' or a value from '128' to '65520' for this parameter. Note that you must define a suitable value for this parameter so that the product of the transfer block length and the transfer block count does not exceed 65520 bytes.

C=99

This parameter defines the transfer block count for the Send processing. (Optional)

Specify '0' or a value from '1' to '99' for this parameter. Note that you must define a suitable value for this parameter so that the product of the transfer block length and the transfer block count does not exceed 65520 bytes.

Note

  • You can default either 'B=' (transfer block length) or 'C=' (transfer block count). However, you cannot default both of them at the same time. Be sure to define at least one of the two.

  • When you define '0' for both 'B=' (transfer block length) and 'C=' (transfer block count), HULFT automatically calculates and sets the size of the transfer unit (the transfer block length x the transfer block count).

  • If you define '0' for only 'B=' (transfer block length) or only 'C=' (transfer block count), an error occurs.
