From Z85, base85 (fromz85)

[ 1 Description ] [ 2 How does it work in the search window? ] [ 3 How does it work in LINQ? ]

Description

Creates a byte array from a valid Z85 string. This is the inverse of the To Z85, base85 (toz85) operation. For more information about byte arrays, see the Make byte array (mkboxar) operation.

How does it work in the search window?

Select Create column in the search window toolbar, then select the From Z85, base85 operation. You need to specify one argument:

Argument	Data type

Argument	Data type
Z85 string ^mandatory	string

The data type of the values in the new column is boxar(int1).

Example

The examples in this article use values in a data table generated from the following CSV file.

The examples in this article use values in a data table generated from this CSV file. If you want to try the example for yourself, download the file and upload it to your domain clicking Data upload in the navigation pane. Name the new table my.upload.sample.data and select Current date as Date parsing type. Learn more about uploading data in Uploading log files.

After receiving the confirmation message, you can access the table from the Finder, selecting my → upload → sample → data. When you upload data from a file, all the information is included in a single column called message. To split the values into different columns, you can use the Split operation. Click Toggle Query Editor in the search window toolbar and paste the following LINQ query to save time:

from my.upload.sample.data
select split(message, ";", 8) as Z85String

In the my.upload.sample.data table, we want to transform the strings in the Z85String column into byte arrays. To do it, we will create a new column using the From Z85, base85 operation.

The arguments needed to create the new column are:

Z85 string - Z85String column

Click Create column and you will see the following result:

How does it work in LINQ?

Use the operator select... as... and add the operation syntax to create the new column. This is the syntax for the From Z85, base85 operation:

fromz85(Z85_string)

Example

You can copy the following LINQ script and try the above example on the my.upload.sample.data table. As said above, keep in mind that you must download and upload the file provided before to your Devo domain.

from my.upload.sample.data
  select split(message, ";", 8) as Z85String,
    fromz85(Z85String) as Z85Array
