Bad parameter in the CFTSEND.
If, for example, you wish to send a file of which the record length is 1000 and which in the parameter setting of CFT you coded a CFTSEND with parameter FLRECL=80, there is a risk of abnormal stop of the CFTTFIL1. If your partner wishes to receive only the first 80 characters of each recording, it must code FLRECL=80 in the CFTRECV, it is supported by CFT
