/*
* parse is the local implementation of GCI_parsetree below. Most parameters
* are in *cb. Have a look at callblock at top of file or at GCI_parsestring
* below.
* itemnumber is the iterator of the container item or array item, the later
* always has number 1.
*
* The function loops over a type structure tree, the current node name is
* placed in cb->buffer. We do a depth-first iteration.
*
* Indirect array[x] are replaced by a combination of
* indirect container[1], array[x]. This allows a better addressing later.
* The indirect container is flagged as "generated" in this case.
*
* THE GENERATED TYPES MAY HAVE ILLEGAL BIT SIZES. IT ISN'T CHECKED ALWAYS!
*
* Return values:
* GCI_OK: Everything is fine.
*
* In case of an error cb->buffer will contain the
* variable's name where the problem raises first.
*
* GCI_MissingName: A variable's name isn't set. This is the equivalence
* for GCI_MissingValue in the type parsing step. The
* system may or may not raise a NOVALUE condition instead
* depending on the implementation.
* GCI_BufferTooSmall: The variable's name buffer cb->buffer can't hold the
* complete variable's name or the type string exceeds
* 256 byte.
* GCI_IllegalName: The variables name in cb->buffer is illegal in terms of
* Rexx. In general, the basename of GCI_paretree is
* wrong.
* GCI_RexxError: An unexpected error is returned by the interpreter
* while trying to access Rexx variables.
* GCI_UnsupportedType: Wrong type of input, e.g. FLOAT31 or the empty string
* in a type description string. Another reason is an
* internal error since the default sizes for "unsigned"
* and "integer" are not supported.
* GCI_WrongInput: Strange characters occur in the input string as the
* bit size of the type.
* GCI_NumberRange: Number to small or big to fit into the desired type
* with the desired destbyte-size. This applies to the
* element count of an "ARRAY" or "CONTAINER" type size
* or the bit size of the plain type.
* GCI_NoBaseType: The type won't fit the requirements for basic types.
*
* And there are numerous other possible errors returned by cb->callback.
