advise how to encode a matrix in which fields can take one of the values of the set {-1,0,1,2,3,4} (five states in total), I would like to have some function that can encode a matrix of the form:

| -1,0,1,2,3,4, -1,0,1,2,3,4 |
| -1,0,1,2,3,4, -1,0,1,2,3,4 |
| -1,0,1,2,3,4, -1,0,1,2,3,4 |
| -1,0,1,2,3,4, -1,0,1,2,3,4 |
| -1,0,1,2,3,4, -1,0,1,2,3,4 |
| -1,0,1,2,3,4, -1,0,1,2,3,4 |

save to several integers: int arr[6] = {xxxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx}, with the least amount of computational effort

Show me an example of your matrices.

| 4,4,1,2,1,1, 1,1,1,1,1,1 |
| 4,4,1,2,1,1, 1,1,1,1,1,1 |
| 4,4,4,2,1,1, 1,1,1,1,1,1 |
| 4,3,3,3,3,3, -1,-1,-1,-1,-1,-1 |
| 3,3,3,3,3,3, -1,-1,-1,-1,-1,-1|
| 3,3,3,3,3,3, -1,-1,-1,-1,-1,-1|

next:

| 4,4,1,2,2,2, 1,1,1,1,1,1 |
| 4,4,1,2,2,2, 1,1,1,1,1,-1 |
| 3,4,4,2,2,2, 1,1,1,1,1,-1 |
| 4,3,3,3,3,3, 1,1,1,-1,-1,-1 |
| 3,3,3,3,3,3, -1,-1,-1,-1,-1,-1|
| 3,3,3,3,3,3, -1,-1,-1,-1,-1,-1|

I want to compactly store data - one line, one integer

Shift it into the positive region by 2 units to remove 0 and -1 (followed by restoration after reading) and you can easily form an integer.

Well, let the set be {0,1,2,3,4,5} - it does not matter, it is important from this group of digits to get an integer, if at this stage I have a 12x6 matrix, you can get something in the form:

| 4,4,1,2,1,1, 1,1,1,1,1,1 | = 2147483647 - 441211111111/2

seems to fit into int, but I don't know, what if you want matrix 100x6 ;)

SZY: from the Help: Internal representation of int is a long integer of size 4 bytes. Integer constants can take values from -2147483648 to 2147483647. If the constant exceeds the specified range, the result is undefined.

 
Well, you still have string variables to spare, although they will be slower. But 0 and -1 must be removed.

Yes! So far there are only string variables - the algorithm itself is still on "paper", I am preparing data for uploading to a file, but then we will need to analyze the data, and that's where speed is needed, while I think how to unload to int instead of stringi
 

Usually DBMS store group data as a string. The processing speed with large volumes is a pain in the ass. I haven't followed what happened with Clarion, look it up - C compatibility was top-notch there.
