BLAPP is coded strangely and so initially opens the data set with only
the name parameters set. That causes the FQMATC message I suspect. But
then BLAPP depends on low-level messages to tell about errors and so one
cannot tell which of the many OUVOPN calls is actually failing.
The FREQID parameter is put in the object during the initialization
phases (after the first open call). But the SUBARRAY adverb never gets
put in the object. That might be the real problem. Let me work over
the task some to improve the error reporting and to put the SUBARRAY
adverb in. A MNJ tomorrow will let us try again on your data.
