Generating Numbers automatically

I'm using Access 2002.
I have a field called Job No.
It is a text (data type). The reason being that there is an "I" in front of
each number i.e. I1234 I1235 etc
The problem is that when the user enters a new record, he/she has to know
what the last recorded job no. is present in the database, in order to then
assign the next sequential job no. So its a manual process.
I don't want to seperate the "I" component from the Job No. field in order
the make the field an autonumber datatype.
Is there some code I could use to allow the system to somehow automatically
assign the next sequential number incorporating the prefix "I" to each
number ?
thank you for any help.

Thanks for the advice. I think I will simply go with the number and remove
the "I" as you suggested.
I actually added +1 to that formula - eg: DMax("FieldName ", "TableName" )+1
to give me the next sequential number.


if you follow this route you might just as well use autonumber rather
than DMax. I think this is what Rick was suggesting. The autonumber
route is more reliable if several users can add records at the same
time.

The two methods behave differently if records with the highest numbers
are removed - DMax will reuse the numbers whereas Autonumber will only
do this if the database is compacted before any more records are
added.

But how do we do compact programatically ?

I'm building a maths program for year 6 children. Problem with division - I generate a random number between say 1 and 1000. I want to generate another random number which when divided by the first number gives a whole number answer. Any Idea how I could do this? Obviously generating prime numbers is a bit of a problem as well! Cheers, Jack

I am at my wit's end. I want to generate a certain number of random numbers. This is easy, I can repeatedly do uniform(0, 1) for example. But, I want the random numbers just generated sum up to 1 . I am not sure how to do this. Any idea? Thanks.

What is the correct method for generating 2 independent random numbers? They will be compared whether they are equal. What about this method: srand(time(0)); int r1 = rand(); srand(rand()); int r2 = rand(); bool f = r1 == r2;

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
