Marco,
As some previous replies were saying, the behaviour you describe is normal
and documented. The explanation for this is found in the "REPLACE" Basic
function, which is the equivalent for the angle brackets notation at the
left of an assignment operator ("=") for dynamic arrays handling.
For more information, please refer to the Basic documentation manual (File
"BASIC.pdf" in the CDROM library)
Here is an excerpt of the documentation :
----
REPLACE function
Syntax
REPLACE (expression, field#, value#, subvalue# { , | ; } replacement)
REPLACE (expression [ ,field# [ ,value#] ] ; replacement)
variable < field# [ ,value# [ ,subvalue#] ] >
.../...
In IDEAL, PICK, PIOPEN, and REALITY flavor accounts, if replacement is an
empty string and an attempt is made to append the new element to the end
of the dynamic array, field, or value, the dynamic array, field, or value
is left
unchanged; additional delimiters are not appended. Use the EXTRA.DELIM
option of the $OPTIONS statement to make the REPLACE function append
a delimiter to the dynamic array, field, or value.
.../...
----
The fact is that "UniVerse" is mainly designed to reproduce the behaviour
of legacy products in the "Pick" family. In this case, the implementation
of the "INFORMATION" and "IDEAL" flavour followed the default behaviour in
"Pick" native products.
I hope this answered your question.

Hi All,
Consider the program:
A = ''
A<-1> = ''
A<-1> = ''
A<-1> = 3
A<-1> = ''
A<-1> = 4
PRINT A<3>
I expect it output '3' but it outputs '4'. Whats the explanation? I'm on UV
9.6 [NT] running information flavour.
Regards,
Marco
