Hi Peter,

After much trial and error I have finally made a REXX command to both 
OCR a tif file and then open the resulting txt file in StarOffice.
I named the command  tes.cmd and have written it as follows:

/*program for running tesseract*/
SAY 'number'
PULL nbr
parse arg program
program 'C:\ocr\tes  c:\ocr\'nbr'.tif' nbr
parse arg program
program 'D:\office51\soffice C:\'nbr'.txt'
exit

I guess it is poor programming, but it works. At a command prompt I type 
"tes" and it asks for the number.
If I have a scanned file in C:\ocr  e.g.  001.tif, I just have to type 
001 and tesseract converts it to 001.txt in C:\ and then Staroffice is 
opened displaying the text file.

Thanks for the help,

Alan

you don't need to know REXX to use REXX...
just save the script as 'ocr.cmd' somewhere on a path;
edit the user defines sections like:

/* user defines below */

extlist= 'tif fax'	/* list all target extensions to process */
dirlist= '\scanner \scanner\out' /* list all target dirs to
process */
logdir= '\logs\' /* target dir for logs, NEEDS trailing '\'

what type of files do you wish to process ?
current default is to process *.tif and *.fax

to ALSO process 'jpg' extensions, edit like:
extlist= 'tif fax jpg'

where are the source files ?
dirlist= '\scanner \scanner\out'

to ALSO process all faxes in \pmfax add \pmfax to the list like:
dirlist= '\scanner \scanner\out \pmfax'


current default is to process all above file types as present in
\scanner
\scanner\out

dirs on current drive

where do you wish to log what's done ?
current default is
\logs\

as well, supply path to the tessarc executable:

ocrdir= '\ute\tesseract\usr\bin'        /* where is t exe ? */
'SET TESSDATA_PREFIX=F:/ute/tesseract/usr/share/' /* t's libs are there */

/* user defines end */

when you run it, it will find ALL defined file types in ALL defined
sirectories, and, ocr them

so, process/scann whatever, as many as you care, when scanning is
completed, run the script, the script will find all files with defined
extension, and, ocr them

I think...

I tried with some fax files, and, seems to have worked

Hi Voytek.
I've been able to make a REXX program to do what I want as noted in my 
other Emails today. It's not good programming but it works well.

Thanks for all your help. No doubt I'll use your info for something.

Regards,

Alan
