Is there a reason for having "does not match" and "does not exist" considering there is the choice of "if" or "unless"? In other words isn't:
"Delete field 999 unless 999$l matches NASH"
equivalent to
"Delete field 999 if 999$l does not match NASH"
?
Your question and your example do not match. You are not comparing match and exist here. Testing for 245a does [not] exist is different from 245a does [not] match 'test'.
The example I used was "match"/"does not match", but the same holds true if we use "exists"/"does not exist" too: "Delete field 999 unless 999$l exists" equivalent to "Delete field 999 if 999$l does not exist" -- You are receiving this mail because: You are watching all bug changes.
