Suite au message de Jean-Marc Monnez (monnez.jean-marc@AGORA.MSA.FR):
Hi,
try :
carstart=10
carlength=6
varlength=${#var}
((tokeepr=varlength-carstart+1))
typeset -R$tokeepr foo=$var
typeset -L$carlength bar=$foo
var1=$(print $bar) # Strip spaces in case var is less than 15 cars
Should work in ksh 88.
