   Try   
      
     a="some text"   
     echo "${a}more text"   
      
   If you omit the braces here, the shell thinks the variable name is   
   ${amore}.   
      
   But most of the time these braces are just cosmetic (so it's easier to   
   read, perhaps).   
      
   The runscript syntax is just the Bash syntax (/sbin/runscript runs   
   bash), so you can get more info in "info bash" and any bash tutorial you   
   can find on the net.
