COBOL System Limits
This section lists the maximum size of various parameters used in this
COBOL system. The left-hand column gives the affected parameter, and the
right-hand column notes the maximum value allowable in the indicated unit
of measure.

This is limited by the number of fields and/or the levels of occurrence.
It is not possible to give an actual limit, but exceeding the limit will
result in an error when you compile your program.
