Hello Jacques,

Can you please  show me where I should add Scanner dynamic library ?

Thank you very much in advance

Page 4-15 of the Barcoding SDK documentation reads as follows

Installation
The dynamically linked library, SCANNER.DYL, needs to be copied to the root of the Workabout. Also, if you are using the following functions in the supplied module, SCANM.OPO should be copied to the \OPO\ directory on the Workabout. To access the functions in the separate module, without OPLLINT flagging errors, you should also include SCANM.LEX in your project. Both of these files could be included in your ODE project and marked to copy to the Workabout when running. 

Hi Jacques,

Thank you very much for your help , it's ok now I can scan Barecode

Best regards

Hello Jacques,

Can you please advice me about  this concept :

First, I will save database products  in (M:\dat ) psion

Second ,I do program for :

           1) scanning barcode of product 

           2) open database and show details about product wich is scanned

          3) close database  and write in other file  product scanned

I do not foresse any issues

OK, great 

Good afternoon  Jacques,

Can you please show me how save Program in ROM or Backup battery  because when I  remove the battery I  lose the  program

Thank you very much

ROM stands for Read-Only Memory. In other words, you cannot write data to this media.

vvvv

I Important:

When the main batteries and backup battery are removed, all the information in the internal memory (RAM) is lost. Before removing both batteries, you should therefore copy any important information in the internal memory to an SSD or PC.

If you plan not to use the Workabout for long periods of time, it is best to copy all the data on the internal disk (M:) to an SSD and then remove both the main and backup batteries.

vvvv

Have considered storing your programs and data on a [FLASH or RAM] Solid State Disk (SSD)?

                or

Please take a moment to read the below attached PDF document:

Hi everyone ,

Can some experts help me to resolve  problem in this program,it would be much appreciated

I'm trying to compile a sample code below on an old Psion Workabout MX (2MB)

I hoppe this code open file(file has 2 field Ref and Design ) , reasrch Ref    and show Design

for example if user writes 32546987

program must show ARTICLE

Ref :32546987

Design : ARTICLE

thank you  very much in advance

PROC openfile: (title$,reff$)

     local f%

IF NOT EXIST(title$)

print "erreur"
CREATE title$,A,string$,string$            REM si le fichier n'existe pas on le crée


ELSE

OPEN  title$,A,Ref$,Design$      REM ouvrir le fichier des article qui contient 2 champs :


   if f%=Find (Ref$)

    
   print "design",A.Design$     REM  probleme
   
   
   

    endif
    
  close
endif
 
ENDP

,

OPL does not interpret your IF f%=FIND(Ref$) statement like a C program would

Indeed, in OPL, assignement(s) cannot take place within an IF statement.
You need to do a two steps job

f% = FIND(Ref$)
IF (f%)
  PRINT "Design", A.Design$
ENDIF

Hi Jacques ,

Thank you very much for your help
