Since you want a "substring"-function you may be interested in knowing you can nest these expansions like i.e. this:

Code:
${var##{var%%??}}      # only the last 2 characters of any string
${var%%{var##??}}      # only the first 2 characters of any string

You can use these or similar for subsequent expansions, i.e.:

Code:
${var:2:3}      # substring in ksh93-notation to emulate
var=${var##??}   # cut off first two characters
${var%%${var##???}}   # display first 3 characters of resulting string

From the version string of your ksh88 i guess you use AIX. You have a ksh93 available per default in /usr/bin/ksh93.

I hope this helps.

NAME
diagmond - Support Tools Manager daemon SYNOPSIS
/usr/sbin/stm/uut/bin/sys/diagmond DESCRIPTION
The Support Tools Manager (STM) provides three interfaces that allow a user access to an underlying toolset, consisting of information mod- ules, firmware update tools, verifiers, diagnostics, exercisers, expert tools, and utilities. STM uses a monitor ( diagmond ) to manage launching and controlling tools as well as remote file system accesses. Diagmond keeps track of the system hardware configuration which includes the list of tools available for each device. It also keeps track of which tools are currently executing or have been executed on each device. Application Usage This daemon will be deprecated on new server models. Please use System Management Homepage (see hpsmh(1M)). OTHER FILES
