Concatenates text values in an explicit order. If the result would exceed 256
UTF-8 bytes, concatLong truncates the result at a Unicode code point boundary
and appends an ellipsis character. Use concat when overflow should fail
instead of being truncated.
value: the text values to concatenate.
Examples
table T = extend.range(40)
T.Part = "abcdefghij"
result = concatLong(T.Part) sort T.N
show scalar "Truncated text" with result
Remarks
The concatLong function requires sort or scan to specify the order in
which values are concatenated.
The result is still an Envision text value and is limited to 256 UTF-8 bytes.
Truncation preserves Unicode code point boundaries.
