C++ program. However I need to transform EBCDIC code which my program reads
to transform it to ASCCI code so I did not found any other way to perform such a
transform. I wonder if there is a class or an option of a component
that allows EBCDIC to ASCII transformation. In case I should write some
code to build a component that perform such a conversion, I wonder if
someone could help me with some code sample.

Which of the six or so (incompatible) versions of EBCDIC do you need? Once you've chosen a codepage, the technique is to create a 256-entry lookup table which, when indexed by EBCDIC code, yields the corresponding ASCII code.

I don't remember whether EBCDIC <-> ASCII is a 1-to-1 mapping or not. There may be holes or ambiguities.

EDIT: bithub's response is a good place to start, but again, I have no idea which variant of EBCDIC is used for those tables and it may not be the one you need.
