Thanks Corona,

I'm using Korn Shell on Microsoft Windows Services for UNIX 3.5 which supports
Sun Microsystems Solaris versions 7 and 8
Red Hat Linux version 8.0
IBM AIX version 5L 5.2
Hewlett-Packard HP-UX version 11i

Thanks for the tip about the backticks, sterr redirect and the while read ... I'll change that.

Yeah, the file is cumbersome Smilie. As for the splitting, each /^ST/ is a new group, I had taken the {100000} to be the max number of times to execute the csplit.

Yes, two non-word characters in a row, is a blank field

Hope this clarifies the structure of the file ... the initial file is approx 3 million lines
Code:
GS*IN*TPU*TPM*110303*0634*65433*X*002000 #there are approx 75K GS to GE groups
  ST*810*0001  #potentially thousands of ST to SE groups, I have to relate the ST/SE group to the GS line
     N1*SU*TPUNAME*92*TPUCD21 
     N1*SE*SELNAME*92*789

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
