Re: The result of VARIABLE[1,3] + 0
I don't understand. What is this numeric variable. I got the reply '42'. To understand that response, you'll have to read The Hitchhiker's Guide To The Galaxy. Any attempt to explain it outside of that context would be futile.

Re: The result of VARIABLE[1,3] + 0
There is a numeric type or datum as some people call it. Since we are talking MV here and not specifically one vendor. If you look at the opcode of an ADDS machine there is a code for LOADS (string) and also a seperate one for LOADN (numeric). This implies that there are in fact two seperate types of variables. If you inquire into the frame where the variable map is being stored as it's running (workspace not object code) you will see that yes a string variable starts with a 09 and a numeric I forgot I think its a 01 or 02 ... At any rate, its not stored as a string while running, but rather I believe its probably stored based on whatever the last action was on it. A numeric action returns a numeric value and is stored as a numeric. A string action like concatenation would probably switch it to be stored, at that moment, at any rate, as a string. I didn't test *this* behaviour explicitly, so I'm not quite sure.

RE: The result of VARIABLE[1,3] + 0
Marco, Sounds like a bug inwhatever pointrelease you are running. What happens if you say B = A[1,3] * 1 ? I would be very worried about a runtime errorfrom '123' + '456'. Not good.

Re: The result of VARIABLE[1,3] + 0
I tried this on a MCD spirit, D3 W2kand AP-Pro as well and got the '1' and 567 that we're all getting. It's been affirmed here and other places that MV considers everything as a text variable (keep file handles and arrays out of this discussion) and its numerological properties come into play only when we expect it to behave as a number. Thus X="ABCDEF123IKIJIJ" ; Y="456ABCDEFG" PRINT (X[7,3])+(Y[5,3]) would produce the 579 as well. This brings up another aspect of the text/string situation: Consider this A="00"[1,3] ;*zeros for both lines B="00"[1,2] PRINT (A=B) and you would expect to get false as textually speaking 000 is not 00. But left alone, these 2 variables can be concluded to be numbers and thus equal even though their lengths are different. my 1 cent. - Original Message - From: Marco Manyevere To: [EMAIL PROTECTED] Sent: Sunday, February 01, 2004 11:13 PM Subject: The result of VARIABLE[1,3] + 0 Hi All, What is the correct interpratation of A = '001' B = A[1,3] + 0 PRINT B On UV 9.6 I get 0010 contrary to my expectation of 1.

RE: The result of VARIABLE[1,3] + 0
Title: Message Hi Marco, Universe doesn't use the + for concatenation, it uses the : (colon) symbol eg. '123':'456' will result in '123456'. Both these examples come up with the expected results (1 and 579) on version 10.0.2 (UV personal edition, Linux) and also on 10.0.8 on Tru64.

are you looking for a number.. because there may be something else. check for num... then remove the third place ie if num[1,3] then print else error -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Marco ManyevereSent: Sunday, February 01, 2004 8:14 PMTo: [EMAIL PROTECTED]Subject: The result of VARIABLE[1,3] + 0 Hi All, What is the correct interpratation of A = '001' B = A[1,3] + 0 PRINT B On UV 9.6 I get 0010 contrary to my expectation of 1.
