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

NAME
Locale::Codes::Script - standard codes for script identification SYNOPSIS
use Locale::Codes::Script; $script = code2script('phnx'); # 'Phoenician' $code = script2code('Phoenician'); # 'Phnx' $code = script2code('Phoenician', LOCALE_CODE_NUMERIC); # 115 @codes = all_script_codes(); @scripts = all_script_names(); DESCRIPTION
The "Locale::Codes::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924 four-letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying scripts. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $script = code2script('phnx','alpha'); $script = code2script('phnx',LOCALE_SCRIPT_ALPHA); The codesets currently supported are: alpha, LOCALE_SCRIPT_ALPHA This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician. It also includes additions to this set included in the IANA language registry. The Zxxx, Zyyy, and Zzzz codes are not used. This is the default code set. num, LOCALE_SCRIPT_NUMERIC This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician. ROUTINES
