The idea of controlling the RENT checks is a good idea, but we already have a couple of customer requirements for this on the HLASM requirements list (although not on the RFE system) so there's no need for an RFE, thanks. I'm happy to move it up in the list now that it's been mentioned again. It's not the existing RENT/NORENT option which needs to be supported on ACONTROL, because that specifically affects whether checking is enabled for CSECT, but does not affect checking for RSECT, which is always done. What we propose instead is a new FLAG(RENT/NORENT) option which could be used to enable or disable the existing check. Implementing this would be totally routine except that for compatibility reasons the default must be FLAG(RENT) which would require the corresponding option bit to be set on, but the spare flags in the existing ASMADOPT installation defaults module are all currently zero. (It would be very messy to treat it as a special case and reverse the bit settings). We would therefore need to add a sub-level indication to the ASMADOPT module so that we can detect whether it was built before this change and if so set the default to FLAG(RENT) dynamically.
