Dear Ron,
I had forgotten to say that in some circunstances it is necessary to
specify that the rule could avoid parse 1, 2, 3... of the letters.
For example, we have the string bellow and following a rule that parse
after K. If I specify the possibility of one (1) lost parsing, we
should have as result:

ASADASDASKASSASADASASADKASADASASAKDDAASASKASSADAD ASKSASA

ASADASDASK
ASSASADASASADK
ASADASASAK
DDAASASK
ASSADADASK
SASA
ASADASDASKASSASADASASADK
ASSASADASASADKASADASASAK
ASADASASAKDDAASASK
DDAASASKASSADADASK
ASSADADASKSASA

Do you have any idea how to implement that in your script?
Thanks in advance,
Luciano

It would just be a matter of combining the results from the array we generate.

Examining your example result, it appears as if you want to have both the
original output with the output relevant to the number of "skipped" parsing's
below it.

Since this is getting more complex, I have taken the liberty of also outputting
the rule(s) being used; and separating the original output from the output with
the "skipped" parsing's.

This has required some modifications so I am posting the entire macro as it
presently exists.

Eventually, it might be useful to input the parameters (rule(s) and number of
skips) via a user form, instead of multiple Input Box's as I've done so far.

Dear Ron,
You are correct that it would be better to input the parameters (rule
(s) and number of
skips) via a user form, instead of multiple Box. It would be great to
select the rules and eventually skips. Could you help me with this?
Thanks in advance,
Luciano
