During the format definition the decoded string represented by #DS does not change.

Using Format Output in Format Definition

The input used by the above functions to define the code formatting usually corresponds to
the decoded code (#DS). Actually, the formatting expression of each function can also
format the result (output) produced by a preceding code formatting.
The format output is represented as follows:
#F<n>, where:
<n>
#F
= format output
Being Format 5 not included in other format expression, the format number is in the range
1-4. Furthermore, since a format expression operates upon the output of the preceding
formats, the expression defining Format 1 will never contain the result of another format.
Example
The following expression is used to define Format 3:
#DS + FSTR<#F2, 6173, 6263, 0>
The expression input consists of the decoded code and the result produced by Format 2
(#F2).
The FSTR function searches for a defined substring within the #F2 result; then, it
concatenates this substring and the decoded code. The result corresponds to #F3 output.
