Data reported using ERF version 2.2 for contaminant and fish disease data can be screened using "Screen.exe". 

Copy the zipped SCREEN package to C:\ICES\screen and unzip the program. The program runs in DOS. The
SCREEN program and a number of valid code lists, "v*.lis" files, will be extracted. 

See the user's guide at http://www.ices.dk/env/programs/screen/screen_doc.pdf for the installing and use of SCREEN.

Please note the first line in a data file:
  00 RF2.2 SV2.23 LR75
  where SV# refers to the program version, and LR# refers to the valid code list release version

Please use the following file name format for a data submission: RLABO_Year_Matrix.Country (for example, MNHS99cs.sw).
Running the SCREEN program produces 3 output files: a report, warning and error file: "filename".rep, "filename.wrn, "filename".err. 
Check these files and correct the data accordingly.
  
Tips for using the SCREEN program
There are a number of options to be used when running SCREEN:

C:\screen>screen [options] <data-set-qualifier> <input filename>

[options]
    -Zh 	gives a list of all options
    -i  	gives a summary of file creation/revisions
    -DE <nnn> 	inactivates error number nnn
    -e1500 	stops the program after 1500 errors
  
Screen is no longer updated since ERF3.2 allows parameters with a length larger than allowed in ERF2.2. 
SCREEN will eventually stop working but until then it can still be used to prepare the file for conversion to ERF3.2.
