Strings

[FraserSmith51]

Hi

I want to use variables to store some short text strings. In fact I would like to have an array of those strings. I have looked through the JalV2 document but I cannot see a way of doing so.

Is it possible to do this and if so could someone please tell me how to do this?

Thanks in advance

Fraser

Hi Fraser,

If you want to make an array of strings in a variable you cannot use the count function so when you store the string, you also need to store the length of the string with it. You can do it by using a record to keep it together.

Below something that I think should work. In this program I fill the string with spaces and make the length 0.

const byte max_strings = 5

const byte max_string_length = 10

-- Record defining string

record my_record is

   byte string[max_string_length]

   byte length

end record

-- Variable declaration

var my_record my_array[max_strings]

var byte index, length

for max_strings using index loop 

   for max_string_length using length loop

      my_array[index].string[length] = " "

      my_array[index].length = 0

   end loop

end loop

Hope this helps.

Kind regards,

Rob

Thanks Rob

I shall try that in the next few days. Off to visit son tomorrow and an early start so I might not get to it this evening but there will be time while away.

Thanks again as ever

Fraser
