[Oorexx-devel] External function file search in Ubuntu
There's been a long thread in comp.lang.rexx in the last few days from someone trying to get external functions to work on an Ubuntu system. This was ooREXX 4.1.2 The user's problem turned out to be due to him making function calls with unquoted function names, which were folded to uppercase by oorexx and then didn't match the actual file mixed-case leafnames - no surprise there. But in the Ref manual section 7.2.1 about file search orders it says Unix-based systems have a case sensitive file system, so files much be exact case matches in order to be located. For these systems, each time a file name probe is attempted, the name will be tried in the case specified and also as a lower case name. The user did also, he says, try with the external function files named in lower case. You can check that if you want in his news post: Date: Thu, 20 Sep 2012 22:08:30 -0400 From: Cruz, Jaime spamm...@bite.me Subject: Re: FINALLY got OOREXX working under Ubuntu!!

Re: [Oorexx-devel] External function file search in Ubuntu
This is working correctly. The function name uses normal Rexx rules for name resolution. If the call name is coded as a symbol, then the name being called is ALWAYS the uppercase version, since all symbols have as an eventual value the uppercase value of the symbol. So calls to foo, Foo, and FOO are all calls to a function named FOO. This all happens before the search for an external function ever begins, so that code is not even aware of the original case. The instruction itself has already folded the name to uppercase by execution time, so the original case is no longer available. If a quoted string is used, then the original case is maintained.

I've raised a Documentation bug (hopefully correctly, I don't understand te new ticketing software), so maybe someone can clarify this in future manuals. Separately from the doc issue, is there any point in making a feature request that in some way - maybe a trace option? - one could have oorexx tell you in succession all the places it looked for a specific-named file? The whole process strikes me as being mind-bogglingly complicated and although descriptions go some way to describe what's being taken into account, actually having a clear understanding of precisely which name of something is being looked for and in what location is ... hard. I'd like to see output something like: trace Search Call NoSuchFunction() 3 *-* Call NoSuchFunction() 'NOSUCHFUNCTION' not found in REXX_PATH 'NOSUCHFUNCTION' not found in PATH 'NOSUCHFUNCTION' not found in ... 'NOSUCHFUNCTION.XYZ' not found ... etc with whatever details are appropriate, preferably showing the exact case and file extensions looked for in the order they are tested in. For things like search in REXX_PATH or PATH, if the oorexx code itself identifies the separate directories involved then I'd rather see those enumerated in the trace output, but if it just uses some system function to search for file x on path y then the environment var name would be enough detail. For a function call where the search is successful I think the trace output shouls also show the location where the item was found. -- Jeremy Nicoll - my opinions are my own -- Got visibility?

Re: [Oorexx-devel] table vs. identitytable
You aren't seeing a difference because you're using the same set of objects. for your indexes. Here is a simple example that will show the difference. i1 = abc i2 = ab||c table = .table~new itable = .identitytable~new table[i1] = Walter table[i2] = Pachl say table~items -- 1 item say table[i1] table[i2] -- Pachl Pachl itable[i1] = Walter itable[i2] = Pachl say itable~items -- 2 items say itable[i1] itable[i2] -- Walter Pachl With a table, both i1 and i2 are the same index because the two objects compare equal. With an identitytable, i1 and i2 are NOT the same index because they are different objects. For most purposes, a table is sufficient for the job. There are some advanced uses, however, where the distinction is important. You really need to have a better understanding of what objects are before I attempt to explain those uses.

But I thought I'd clarify a few things that caught my eye: NEW- Returns an array of all indices contained in the table Both indexes and indices are correct spellings. We talked about this some years ago and decided to always go with indexes. OLD- -hasItem(value)-- OLD- Returns 1 (true) if the collection contains the value at any index position NEW- -hasItem(item)--- NEW- Returns 1 (true) if the collection contains the item at any index position why different (item vs. value)??? Item and value are synonymous here. You can say I want to get the value at index 'x' or you can say I want to get the item at index 'x' The both mean the same thing. The text within the () is a variable name. value is just as good a variable name as item is. There is therefore no *compelling* reason to change the text. In general, I'm not even sure what your delta means. It would seem that you are saying that section 5.3.16 should be changed to 5.3.17?? There are 2 different things being documented. In 5.3.16 the Table class is being documented. In 5.3.17, the IndentityTable is being documented. They should have different text.
