To clarify. I wrote:
"What is REALLY needed is to get rid of the absurd requirement to specify the amount of storage to allocate for datasets! The system should allocate/reallocate according to what is needed in the actual/immediate need for the dataset without dumping the problem to the user! (Of course limited by appropriate resource constraints.)" With that I meant: 1. That there is many cases where an unspecified/undeterminable amount of space is needed for an allocation. 2. That because of the "undeterminable" status (which can be because it's exactly undeterminable or not possible to spend the amount of time to make it determinable) you can't make any rule of how much space it will request at run time. 3. That any ACS rules or other techniques (other than products that catches a x37 at run time) therefore is of limited help. 4. That if IBM have a function that catches an out of space condition and extend the allocated space to the current need it would save an enormous amount of time spend at correcting the error and rerun the jobs. 5. That *limiting* the use of space should not depend on what is written in the SPACE parm. Rather that it's something that any sort of quotas (ACS maybe) connected to the userid and datasetname should handle. 6. This is - more or less - how it works in e g the Unix world. And they are maybe not insane ?
