jBase Open file Fails with Error 128 in the .b File

[Achyuth Balakrishnan]

Hi,

I have a .b file, in which I am trying to open a jBase file with the below syntax. But it fails with error: 128 (which means 'No such file or directory')

OPEN "MODULE.METHODS.SOURCE" TO ibfvar SETTING openErr ELSE

  PRINT "Could not open '":ibfile:"': ":openErr

  GOSUB HELP

STOP

The JEDIFILEPATH environment variable is set to the folder location where this jBase file is..

The MODULE.METHODS.SOURCE is a jBase extended Object. In the MD file setting the fourth Ordinal to "1" means it is an extended Object.

MD file entry is as below. 

D:\Jenkins\workspace\MODULE64_Snapshot>ed MD MODULE.METHODS.SOURCE

MODULE.METHODS.SOURCE

TOP

.P

TOP

001 Q

002 MODULE

003 OBJ\METHODS]MSOURCE

004 1

BOTTOM

.

The SYSTEM file entry is as below

D:\Jenkins\workspace\MODULE64_Snapshot>ed SYSTEM MODULE

MODULE

TOP

.P

TOP

001 D

002 D:\Jenkins\workspace\MODULE64_Snapshot

BOTTOM

.

Both the MD and SYSTEM files are in the same folder (D:\Jenkins\workspace\MODULE64_Snapshot) which is set by the below environment variables.

The MODULE.METHODS.SOURCE folder is in the folder D:\Jenkins\workspace\DPS64_Snapshot\OBJ

set HOME=D:\Jenkins\workspace\MODULE64_Snapshot

set JEDIFILENAME_MD=%HOME%\MD

set JEDIFILENAME_SYSTEM=%HOME%\SYSTEM

set EXIT=%HOME%\OBJ

set JEDIFILEPATH=%HOME%;%HOME%\OBJ

The below line of code when I try to OPEN with the complete path, it works fine.

OPEN "D:\Jenkins\workspace\MODULE64_Snapshot\OBJ\METHODS]MSOURCE" TO ibfvar SETTING openErr ELSE

Can someone please help.

Thank you

Achyuth

So, taking this a step at a time

OPEN 'file' ...

Reads the Definition from the MD for 'file'

Reads the 'Account Definition' from the 'SYSTEM' file

Builds the path to the requested file :

'D:\Jenkins\workspace\MODULE64_Snapshot' : DIR_DELIM : 'OBJ\METHODS]MSOURCE'

So, in theory, identical to the working example where you provide the 'full file path'

Are there any ( redundant ) 'spaces' [ or 'tabs' etc ] in either the 'SYSTEM MODULE' entry or 'MD MODULE.METHODS.SOURCE' item ?

[ Use 'H', in 'ED' to see the Hex value of the contents [ '09' is tab, '20' is Space etc ] ]

Just brainstorming here, but could it be that problem is because the Q-Pointer is referencing part of a path “OBJ\METHODS]MSOURCE” instead of just a file name “METHODS]MSOURCE”? I never tried setting up a Q-pointer like that before, and so I’m not sure.

Hi Pat,

Thank you so much for the reply. I am not working on it anymore. I found a workaround to bypass this issue. I just tried removing the 4th Ordinal (the value 1) and it worked fine.

Not sure if that is the right approach, but it served my purpose.

Once again appreciate your efforts in replying to my query. 

Regards

Achyuth

Could be Bruce [ well spotted ]

Possibly because the Q-pointer contains the Windows 'directory delimiter' '\' [ which in 'C' is taken as 'treat the following character as it's literal value, ie the '\' is no longer treated as a Windows Directory delimiter ]


Happy New Year all
