I noticed that when using findscu.exe and storescu, if the aec title is too long, it seems to get truncated at 16 characters. Is there a reason for this?

For example, the call to findscu.exe is
findscu.exe -ll debug -to 15 -S -k (0010,0020)="010001" -aet "AE" -aec "MWL_SCP_MI_REPORT_7887" "" "5678" cfindpatient.wl

But the called application name in the output is truncated:

The reason is that DICOM PS3.5 defines a maximum length of 16 bytes for the value representation AE (Application Entity).
