Create a link file from a link coverage for WARP

Summary

The AML in this article allows you to convert your link coverages to link files.

Procedure

1. Start a text editor.
2. Copy this AML:
   
   

   Code:
   /* ================================================
   /* linkcov2file.aml
   /*
   /* Convert link coverage to ASCII link file
   /*
   /*
   /* USAGE: &RUN linkcov2file.aml <incover> <outfile>
   /* 
   /* ================================================
   &args incov outfile
   
   arcedit
   edit %incov% link
   select all
   &sv numlinks = [show number selected]
   
   /* Open file for writing 
   &sv outfileunit = [open %outfile% openstat -write]
   &if %openstat% <> 0 &then &return Error %openstat% opening file %filename%
   
   /* Loop through all links, check for identity links, write file
   &do i = 1 &to %numlinks%
     select $recno = %i%
     &sv fromxy = [show link [show select 1] from]
     &sv toxy = [show link [show select 1] to]
     &if %fromxy% = %toxy% &then ~ 
           &ty Identity link - not written to output 
           /* If identity tics, do not write
     &else &sv writestat = [write %outfileunit% %fromxy%,%toxy%]
   &end
   
   /* Close write file
   &sv x = [close %outfileunit%]
   quit
   &return
   

   
   
3. Save the file as linkcov2file.aml. Make sure your editor does not append any other extension.
4. Run the AML in the same workspace as the link coverage.

   Arc: &RUN linkcov2file.aml mylincov mylinkfile.txt
