EXTBININT{(*NO | *YES)}

The EXTBININT keyword is used to process externally described fields with binary external format and zero decimal positions as if they had an external integer format. If not specified or specified with *NO, then an externally described binary field is processed with an external binary-decimal format. If EXTBININT is specified, optionally with *YES, then an externally described field is processed as follows:
DDS Definition
RPG external format
B(n,0) where 1 ≤ n ≤ 4
INT(5)
B(n,0) where 5 ≤ n ≤ 9
INT(10)
By specifying the EXTBININT keyword, your program can make use of the full range of DDS binary values available. (The range of DDS binary values is the same as for signed integers: -32768 to 32767 for a 5-digit field or -2147483648 to 2147483647 for a 10-digit field.)
Note: When the keyword EXTBININT is specified, any externally described subfields that are binary with zero decimal positions will be defined with an internal integer format.
