2966.0. ""CREATE" function Question " by TKTV27::MINAKUCHI (Atsushi Minakuchi TSC/CSC Japan) Tue Jul 06 1993 06:25

Hi,

My Customer created "Entry-form" like follows.
This Entry-form create Index file (logical name MY_FILE) at Remote node.
He used "LOGICAL" function to specify filename and "CREATE" function to make
Index file at remote node.

The problem is that if he define LOGICAL name over 107 characters, 
"CREATE" function caused error.

I tested this operation ALL-IN-1 V3.0 and VMS V5.5-2.
The error also occurred at my system.

Is there any restriction about logical name length in ALL-IN-1 ?
I think logical name can define 255 characters at VMS operation.

Thanks in advance,

Atsushi Minakuchi (TSC/CSC Japan)

Check logical definition using "LOGICAL" function.

<LOGICAL MY_FILE

Create Index file at Remote node using "CREATE" function.

<CREATE Entry_form_name

    Hi Atsushi,
    
 >%OA-E-DBEOR, Error opening NTT_TEST - File TKTV25"MINAKUCHI password"::[MIN  
 >AKUCHI.WORK.WORK00001.WORK00002.WORK00003]�         
 >-RMS-F-ESS, expanded string area too small                                   
    
    I think that the problem has been caused by the expanded string being
    too long ie TKTV25"MINAKUCHI password"etc. is far too long when the
    logical is translated.
    
    It's not an ALL-IN-1 restriction but an RMS or OpenVMS is my guess and
    has nothing to do with the length of the logical name in this case.  I
    can't remember but there is a restriction on the logical name length
    within ALL-IN-1.
    
    I am sure that someone in IOSGland will come back with the full answer.

    Actually, this error is an RMS error which tells you that too small an
    ESA buffer has been provided.
    
    With RMS you specify in the NAM block the size and address of a buffer
    for the expanded string and possibly for the resultant string. These
    are used for $PARSE and $SEARCH operations to return the filespec and
    filename respectively. Some RMS operations such as $OPEN and $CREATE
    perform an implicit $PARSE and/or $SEARCH operation.
    
    In this case, the filename RMS is trying to return is larger than the
    ESA buffer. The OARMS code sets up a maximum buffer length of 100 so
    this is the limitation. Filenames can be up to 255 characters.
    
    So, I suggest submitting an SPR if this is a real problem for you.
    Otherwise, keep to less than 100 characters.
    
    Paul.
