Questions that come to mind upon reading your post:
1. Why do you need to read the data set before deleting the records?
2. What program or utility are you expecting to get RC 8 with?
3. Why do you have to use File Aid?
4. Why, after almost 8 years on this forum, do you call it a "file"? z/OS has tape files and Unix System Services files -- everything else is a data set.
The quick and easy way to delete the records in the data set is to use IEBGENER with SYSUT1 DD DUMMY and SYSUT2 being the data set. No, it does not use File Aid and no it does not read the records before deleting them, but it will remove all records. And you may -- or may not -- get RC 8 depending, again, upon what program you are using to read the data set.
If you are doing more than described and file aid provides that facility then do your file aid stuff but choose batch instead of online and edit the job before submission to produce a JCL error so that you now have the first part of your requirement.
