Operations on alphanumeric items, such as INSPECT and UNSTRING, can be optimized by compiling the COBOL program with -b option. This option causes isCOBOL to handle the data item using a byte array instead of an object, causing the string management to be faster.
iscc -b myprogram.cbl
java com.iscobol.compiler.Pcc -b myprogram.cbl
NOTE: The -b option avoids you to use national data items.
