The dynamic cleanup module (at least in IMS V9) is DFSMRC20. So Mr. Clean can go away forever provided you remove the entry from IEAVTRML. The other thing I have to correct is the "nasty abends" statement. It had been so long since I ran into this that I forgot that the consequences were much worse: "If you do not remove the name DFSMRCL0 from IEAVTRML before you delete module DFSMRCL0 from SYS1.LPALIB, your z/OS system will not start." So that tells me for sure it is somewhere in Barbara's system search order or she is not using the IGC0001C/IEAVTRML she thought she was using. -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS mailto:[email protected] Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://expertanswercenter.techtarget.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
