[Cobolforgcc-devel] MOVE subroutine in UNSTRING

[Steven O. E. <so...@so...>]

Tim,

The UNSTRING statement, conceptually at least, has an embedded MOVE in
it.  I understand from recent messages on the mailing list that you are
working on MOVE.  Please let me know when you have a first draft, so
that I may "borrow" from it when coding UNSTRING.  Meanwhile, I will
work on test cases, and rest of the prototype.  Here is the relevant
clause from the 1985 Standard, referring to a subset of characters from
the source area to be moved to one of the receiving areas.

	6.27.4  General Rules

	(13) c.  The characters thus examined (excluding the delimiting 
	character(s), if any) are treated as an elementary alphanumeric 
	data item, and are moved into the current receiving area 
	according to the rules for the MOVE statement.  (See page VI-103, 
	The MOVE Statement.)

This becomes nontrivial when you consider that the receiving area may be
defined as signed numeric or alphanumeric right-justified.
