Entering commands in PL/I DBCS freeform format

Statements can be entered in PL/I's DBCS freeform. This means that statements can freely use shift codes provided that the statement is not ambiguous.

This will change the description or characteristics of

LIST
NAMES

in that:

LIST NAMES  db<.c.skk.w>ord

will search for

<.D.B.C.Skk.W.O.R.D>

This will result in different behavior depending upon the language. For example, the following will find a<kk>b in C and <.Akk.b> in PL/I.

LIST NAMES a<kk>*

where <kk> is shiftout-kanji-shiftin.

Freeform will be added to the parser and will be in effect while the current programming language is PL/I.
