Either 999,999,999 or 2,147,483,647 -- the actual maximum depends on a compiler option. TRUNC(BIN) allows the binary value maximum of 2 to the 31st power minus 1 while TRUNC(STD) allows the picture size to determine the maximum. TRUNC(OPT) is the other option and in that case, the actual value may not be determined in advance.

Regardless of the setting of the TRUNC compiler option, COMP-5 data items behave like binary data does in programs compiled with TRUNC(BIN).

Adding to Dick's response, unless you absolutely need a sign, unsigned COMP-5 (Native Binary) 9(09) has a maximum value of 4,294,967,295.

COMP-5 was introduced with OS390/COBOL version 2.2 about 10 years ago.
