Varible for element number in an array

[blumash]

I have a array with 20 elemnts , each time I have to store a field to another element " store tran to saltot(x) " , saltot is the array and X is the number of elemnt , how can I use the same command all the time with a varibale that is changing???

Thank's

I'm not exactly clear on what you are saying, but there are several different ways to use variables:

FOR nCounter = 1 TO 20
   saltot[nCounter] = tran
NEXT

Will result in all 20 elements having the value of 'tran' in them

If 'tran' is a table field:

STORE 0 TO nCounter
SCAN 
   nCounter = nCounter + 1
   saltot[nCounter] = tran
   IF nCounter = 20
      EXIT
   ENDIF
ENDSCAN

I understand you need macro substitution "&". What are the names of your fields? If they were like tran1, tran2, tran3 and so on, you could use:

For x=1 to 20
store tran&x to saltot(x)
Endfor

Thank's TheRembler , saltot is a array with 200 element in it , the problem is that evry time I have to store a field called "tran" to element number x in the array , for example
"store tran to saltot(1)" , next time in the program I have to store the same field to element 2 in the same array
"store tran to saltot(2)" , the number is changing & instead of the numbers I need to put a varibale that I change manualy in the program.

Thank's

Hi,

Then Dave understood your problem better than me and gave you good examples. I would only add that you could use 'x' as your variable, like:

x = 1
store tran to saltot(x)

next time, you can change the value of x, let's say:

x = 2
store tran to saltot(x)

Thank's , I solved it & now it's working , there was a stupid thing there , when I wrote "store tran to saltot[x]" it gave an program error massage , then I wrote "saltot[x]=tran" this was ok , I don't understand what's the different & why the first command was an error but doesn't matter the second command is doing the same without a program error.

Thank's

What was the error number and/or error description you got? I tried your original method in both FPW 2.6 and VFP 6.0 without errors.

DECLARE saltot[200]
x=2
tran=55
STORE tran TO saltot[x]
? saltot[x]
