#676 Extend ::OPTIONS .. ERROR to other conditions

[Erich]

::OPTIONS NOVALUE ERROR is of great help during debugging. It would be nice if ::OPTIONS .. ERROR could be extended to other conditions like LOSTDIGITS, NOMETHOD, NOSTRING, or even ANY.

(see related [feature-requests:#656])

[LesK]

One has to wonder why they weren't included to begin with? Btw: All the settings
point to 'digits' of the Package class :-(

[John Bodoh]

I agree with LesK. It should be left up to the ooREXX developer how and when conditions are handled.

[Erich]

Revision [r11937] adds new ::OPTIONS condition subkeywords for ERROR, FAILURE, LOSTDIGITS, NOSTRING, NOTREADY, and ANY.

It changes the secondary subkeyword ERROR to SYNTAX to better reflect that these directives raise a SYNTAX error when set.

Otherwise it closely follows OPTIONS NOVALUE by allowing SIGNAL/CALL overrides and like NOVALUE it doesn't raise SYNTAX if the condition is raised through a RAISE instruction.

ANY enables all of above named conditions plus NOVALUE. Overriding OPTIONS is possible with e. g. ::OPTIONS ANY SYNTAX NOSTRING CONDITION (i. e. all conditions except NOSTRING will raise SYNTAX)

There is no ::OPTIONS NOMETHOD or HALT as these already raise SYNTAX when unhandled.

Revision [r12133] renames incorrectly-named ::OPTIONS ANY to :OPTIONS ALL
Adds more tests to OPTIONS test group
Updates rexxref.

fix SIGNAL test group with [r12134]
