Here is one for all ksh versions:
Code:
#### here filename contain XXXX_YYYY_ZZZZ_DDD.txt as example
while read filename
do

### split filename on "."
extension="${filename##*.}"
[ "$extension" = "$filename" ] && extension=""
noextension=${filename%.*}
[ "$noextension" = "$filename" ] && noextension=""

### split noextension on "_" to AR[0] AR[1] ... AR[lenAR-1]
## ksh93 takes:
# IFS="_" read -A AR <<< "$noextension"
##
## ksh88 needs:
oIFS=$IFS
IFS="_"
set -f
set -A AR $noextension
IFS=$oIFS
set +f
##
lenAR=${#AR[@]}

### Conditions...
if
  [ "$extension" != "txt" -a "${AR[0]}" = "HELP" ] ||
  [ "$extension" != "csv" -a "${AR[0]}" != HELP ] ||
  [ "$ARR[2]" != "WE" ]
then
# UPDATE TABLE ########################
   echo rm "$filename"
fi

done

Remove the echo to run the rm command.

dtinfoaction

dtinfoaction(file formats)												dtinfoaction(file formats)

NAME

       dtinfoaction -- CDE information management actions

SYNOPSIS

       DtLoadInfoLib filename
       Open filename
       DtShowInfoAtLoc
       DtPrintInfoAtLoc

DESCRIPTION

       The CDE Information Management Services support the following information management actions:

       DtLoadInfoLib filename
		 Load  the  information  library  specified  by filename, which can be either a relative or absolute file path. If filename is not
		 specified, dtinfo displays the default information library(s).

       Open filename
		 Load the information library specified by filename.  Remaps to DtLoadInfoLib filename.

       DtShowInfoAtLoc filename section
		 Display the section or topic specified by section contained within the infolib specified by filename.	filename can be  either  a
		 relative  or  absolute  file  path.  section  specifies the information library section in generalized locator format.  dtinfo is
		 started if it is not already running. This corresponds to invoking dtinfo with the -sect option from the command line.

       DtPrintInfoAtLoc
		 Print one or more infolib sections from the desktop. This action is invoked whenever a section or sections is	dragged  from  the
		 book list window in dtinfo and dropped on the printer icon on the front panel.

       These  actions can be invoked from an application using the DtActionInvoke(3) function or invoked from a command line using the dtaction(1)
       utility.
