The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Since the hyphen (identified in the conversion tables as 'subtraction
sign') is ASCII x'2d' but EBCDIC x'60' it will be found within the range
x'00' to x'3f' if, as I suspect, the string passed into the regex processor
(wherever that may be) is evaluated as ASCII instead of EBCDIC.
btw, I like the simple VALUES EXPRESSION format you use for your tests.
Don't know why I didn't think of that and waste my time building common
tables.
Another test clinches it:
values regexp_instr('grave`concern_', '[\x5f-\x60]') -- Result 6
... take the grave out and replace with a space
values regexp_instr('grave concern_', '[\x5f-\x60]') -- Result 14
The grave symbol is ASCII x'60' and underscore x'5f'
The EBCDIC equivalents are x'79' and x'6d' so we shouldn't have found
either.
