#12 "not all input was consumed": string concatenation with & (2002-Standard)

[Luis R.]

X"" (alphanumeric hexadecimals) and NX"" (national alphanumeric hexadecimals) type strings can be concatenated with & as well. I've already made some changes to the tokenizer and grammar so they should count as string literals.

[KrisDS]

[r150] has initial support for concatenation expressions. It is based of what I found in the FCD documentation.

Needs more testing, but already seems to improve the situation quite a bit.

[Luis R.]

Yes, much better! I still found one case where the parser failed:

05         pic x(30)       value "Resident Address" & CRLF.

[KrisDS]

Is CRLF a special keyword, or just an ordinary data item ?

[Luis R.]

CRLF is a level-78 constant in the above line.

Also found this (X"" alphanumeric hexadecimals are concatenateable):

           call staticWINAPI RegisterEventSource
              using by value     0 size 4
                    by reference EVENT-NAME & x"00"
              returning ws-event-handle
           end-call

[KrisDS]

OK, I updated the logic a bit more. It now covers (and tests) the above cases you mentioned.

Any more cases you see which need fixing, or can we close this for now ?

[Luis R.]

Couldn't find any others, feel free to close this.
