Modify a value on a structured array

I have a structured array, i loop through, insert starting values into the fields, then I want to loop back through the array, and modify a specific line of that array. As in

ArrayModify(OrdLine[nsub].FieldIWantChanged) or ArrayChange.... or do I save that line , delete the line in the array, then put the line back, modifying the particular field I need changed.

I am wondering if a memory table - which i know nothing about on pcsoft products - is a better solution. The array I build - is an array of years of a persons life - and contains various values as in, expected salary, various costs, expected inflation, expected tax bracket, etc. etc. . All of the fields or columns of this array are known at start - so I used a structured array to start this - but on other platforms ( i have written and rewritten this app since 1986) , i used what was called a memory table , basically a file with a couple keys (years, age) and a 50 or 60 fields - except its not stored on disk, its created, added to , modified and reported and displayed from memory.

Thanks.

Don

Hi don,

I dont know if what you are talking about is one array of structures, something like this:
My_structure is structure
vari is int
vars is string
vard is date
end
my_array is dynamic array of my_structure

To add values use:
var_int is int
var_int=arrayadd(my_array)

To change the array values use:
my_array[var_int]:vari=1
my_array[var_int]:vars="xxxxxx"
my_array[var_int]:vard=today()

you don't need any special function to change the array values.

Excellent Paulo, thanks. My thought was that since there was a function arrayadd to add the line out there , there had to be something else to modify it. I was writing a quick test to see what happened when I do - what you just advised me to do. Thanks.

Best regards

You only need functions to manage the occurences (arrayadd, arraydelete,.....).
To change the values of the existing occurences you don't need any function.

Hi Don,

In addition to Paolo's reply you can also modify an array in a loop like this:

FOR EACH ensSTBuffer of ar_MyArray
   IF ensSTBuffer.Condition="test" THEN ensSTBuffer.Value=NewValue
END

This saves you the trouble of the use of indexes.

Kind regards,
Piet

Thanks Piet, thanks Paolo, you have both been very helpful.

Kindest regards

Don
