Thanks for the explanation Frank. <*Sigh*> I kinda figured it would be some such reason, even though I wouldn't have done it that way myself, thinking like the application programmer that I am. And thanks for the heads up about MERGE using E32. I didn't RTFM quite enough there and just *assumed* that a MERGE used E15. Related question: Can a plain C subroutine (LE-enabled, not MetalC or SP C) be used as a DFSORT exit routine? If so, what would the fourth exit parameter be set to? "C" like for COBOL, or "N" for none? -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
