I assume you do not have access to ABAQUS Documentation and in particular to ABAQUS Keywords Reference Manual. Therefore, I copy-pasted the description of INC parameter:
"INC
Set this parameter equal to the maximum number of increments in a step (or in a single loading cycle for direct cyclic analysis). This value is only an upper bound. The default value is 100.
The INC parameter has no effect in procedures where automatic incrementation cannot be used (for example, *BUCKLE, *STEADY STATE DYNAMICS, and *MODAL DYNAMIC).
"
(I think that is not a message but rather a copy of a STEP definition from the input file.)
