Getting the value(s) of varibales during the runtime

Question

Dear All
I'm trying with the below listed code to log some information about a
programm process during the Runtime. I would have e.g. a timestamp
the values of some varibales s.o. The sutructure abap_call_stack_entry
has some interesting fields but I get shown #### as value if I use some of them.
The field abdbg-levent provides the form name which is called.
How can get for example the content (value) of a variable within a routine or
form ? Does anybody got an Idea on right using of this structure "abdbg"
or how to solve above mentioned problem?
perform first.
perform second.
perform fourth.
form first.
data latte type i.
latte = 78.
perform akt.
endform.
form second.
data bolo type i.
bolo = 345.
perform akt.
endform.
form fourth.
data sync type i.
sync = 989.
perform akt.
endform.
FORM akt.

Answer 1

CALL 'ABAP_CALLSTACK' ID 'DEPTH' FIELD -1
ID 'CALLSTACK' FIELD tab.
provides useful information about  a programm
and its routines like Programname linenumber etc.
All what I want to have is getting more information
concerning a programm during the runtime.
As I have heard the above mentioned structure
ABDBG provides exactly such things.
And I have problems on using this sructure
because I get characters like ##### instead
of values of variables and so on.
Please look to the structure components
