INDSMOI0 Not enough storage to create
target windows
Explanation: There is not enough storage
allocated to create all the target windows. Each
window must have at least 10K of storage, and
the total cannot exceed the size of the source
window.
User Response: Choose smaller storage
requirements for each window, or choose fewer
windows. Run INDDENV to see how much
storage the source window has.
INDSMOll Target window x already exists
Explanation: Since the target window exists, it
cannot be created again.
User Response: Either specify the target as a
source window also, or choose another target
window.
