problems when a file is opened for readwrite. |
613 | 207 |
For best results, open files either readonly or writeonly. |
1295 | 208 |
|
2921 | 209 |
Also notice, that some OperatingSystems do not fully support |
210 |
positioning a file stream. |
|
211 |
For example, poor VMS does not allow positioning onto arbitrary |
|
212 |
byte boundaries if the file is a variable-record-RMS file. |
|
213 |
(stupid enough, this is the default for textfiles as created by |
|
214 |
some tools ...) |
|
215 |
Therefore, the instance variable canPosition is set according to |
|
216 |
this and an error is raised, if a position: is attemted. |
|
217 |
I know, this is ugly, but what else could we do ? |
|
218 |
||

for VMS users only: |
|
234 |
||
235 |
The #openWithMode:attributes: entry allows additional RMS attributes |
|
236 |
to be passed in the second argument, which must be an array of strings |
|
237 |
as described in the 'creat' RTL Library documentation. |
|
238 |
||
239 |
For example, to create a file with fixed records and recordLength of 100, |
|
240 |
use: |
|
241 |
||
7872 | 242 |
|newFile| |
2921 | 243 |
|
7872 | 244 |
newFile := FileStream new pathName:'<nameOfFile>'. |
245 |
newFile setMode:#writeonly. |
|
246 |
newFile openWithMode:'w' attributes:#('rfm=fix' 'fsz=100'). |
|
2921 | 247 |
|
248 |
since all of the above is private protocol, and it is considered bad style to |
|
249 |
access these from user programs, we recommend subclassing FileStream as |
|
250 |
something like VMSFixedRecordFileStream, and redefine the instance creation |

attributeSpec is an additional argument, only used with VMS - it allows a file to |
|
975 |
be created as fixedRecord, variableRecord, streamLF, streamCR, ... |

976 |
In VMS, if nonNil, it must consist of an array of strings (max:10), giving additional |
|
977 |
attributes (see fopen description). |
|
978 |
Passing a nil specifies the default format (streamLF) - ST/X always invokes this with nil. |
|
979 |
This argument is ignored in UNIX & MSDOS systems. |
