Removing Header and Trailer record of a EBCDIC file

I have a EBCDIC multi layout file which has a header record which is 21 bytes, The Detail records are 2427 bytes long and the trailer record is 9 bytes long.

Is there a command to remove the header as well as trailer record and read only the detail records while at the same time not altering the file itself..something at runtime

NAME
audit - write a record to the audit log SYNOPSIS
cc [ flag ... ] file ... -lbsm -lsocket -lnsl [ library... ] #include <sys/param.h> #include <bsm/libbsm.h> int audit(caddr_t record, int length); DESCRIPTION
The audit() function queues a record for writing to the system audit log. The data pointed to by record is queued for the log after a mini- mal consistency check, with the length parameter specifying the size of the record in bytes. The data should be a well-formed audit record as described by audit.log(4). The kernel validates the record header token type and length, and sets the time stamp value before writing the record to the audit log. The kernel does not do any preselection for user-level generated events. If the audit policy is set to include sequence or trailer tokens, the kernel will append them to the record. RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The audit() function will fail if: E2BIG The record length is greater than the maximum allowed record length. EFAULT The record argument points outside the process's allocated address space. EINVAL The header token in the record is invalid. ENOTSUP Solaris Audit is not defined for this system. EPERM The {PRIV_PROC_AUDIT} privilege is not asserted in the effective set of the calling process. USAGE
Only privileged processes can successfully execute this call. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Committed | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
