How to prevent error 70?

[Mike Doty]

Is ATTRIB + R also applied to the .EXE file?

That is pretty likely... PB/DOS is slated for <U>at least</U> one more major upgrade in the future...

Hi Lance,

I think the CLOSE problem is not too important to me, this is
just an event report, I have tested this by written a short
simply code and cannot reproduce the error.

So your comment on error 70 is: just add "lock shared" for every
file open statement, that sound easy, great.

I still like powerbasic for dos very much, I have spend more that
10 years on it written one accounting software and one word
processing software, and the last one: newdos.exe, all programs
run very fast in modern machine, no one could imaging this 10
years ago!

Hope that Mr. Bob will continues upgrade powerbasic for dos in
future.

I can't answer the CLOSE question without being able to see the and duplicate the problem, but in some cases, refreshing the file subsystem within PB can help, simply by doing a DIR$ on a "dummy" file.

See the posting in the FAQ forum on renaming files on network drives for an overview of the concept.

The Error 70 problems should be solved relatively easily by opening the file(s) with LOCK SHARED mode, to allow non-exclusive access to the file(s).

Hi Davide Vecchi,

1.They occur when the program try to open a file.
2.They occur both in IDE and EXE.
3.More often happen if run two copies of the same program

I also detected another strange error, see this code:
-----------------------------------
CLOSE #2
KILL LASTOPENFILE$
PRINT "DELETE "+LASTOPENFILE$ +"...EMPTY"
CLOSE #1
' CLOSE #2
PRINT #3, "</TR></TABLE>"
CLOSE #3
-----------------------------------
LASTOPENFILE$ was opened as #2 for output, after that
no data has written to it, then it was closed and deleted by
"kill" command, after that, if I issue a "close" command
to close all number of files, internal error 51 occur,

So I changed that command to close #1, close #2 and close #3,
same error 51 at line "close #2", quite strange, that mean we
cannot just any how use a single "close" command to close
all the opened files.

Hi,

Your get an error 70 if You try to open an open file.

E.g. You have started the editor 2 times and one program is
runing .

Chua,
on which statements are you getting the permission denied error ?

Do they only occurr within the IDE and not with the exe ?

Hi everybody, I had not visit this forum for a long time, I am
busy on website operating programming.

Recently someone want to buy my old accounting software written
in pb3.2, due to the fact that nowdays most of the computers are
operate in win98 system, so I make some change on my source code,
I have changed all the print out to html format, great! Easy to
control and able to print to modern printer using IE5.

The only problem is, I always get "ERROR 70 permision no allow"
messages when I run program in IDE, are there any extra file
attrib in win98 system that can not reconized by pb for dos?

Any comments?
