1.24 Subprogram technique
<number of
return jump levels>
<return jump to the
beginning of the program>
Note
For a subprogram return jump with a character string to specify the target block search,
initially, a search is always made for a jump marker in the calling program.
If a jump destination is to be uniquely defined using a character string, it is not permissible
that the character string matches the name of a jump marker, as otherwise the subprogram
return jump would always be made to the jump marker and not to the character string (refer
to example 2).

INT
1 The program is resumed at the "current
program level - 1" (like
parameter).
2 The program is resumed at the "current
program level - 2", i.e. one level is
skipped.
3 The program is resumed at the "current
program level - 3", i.e. two levels are
skipped.

there, then the program branches to the
