   from the early 90's I know about fidonode sysops who used these extensions for   
   advanced scripting  :)   
   ahh .. this reminds me, that there is a slightly chance to find the backup of   
   a system from the named sysop with 4DOS installed   =:)   
   that I probably can use for testing   :)))   
   ...   
   and found it  =:)   
   on one of the around 25 workstation backups  =:)   
   4dos4U.zip and 4Patch.zip and extracted in a directory ...   
   and many scripts with .btm file extensions  =:)   
      
   sample script called vollst.btm   
   ...............................................................   
   rem @echo off   
   set v_tb=   
   for %x in (c d e f g) do (   
     set v_tb=%@substr[%@label[%x:]    ,0,11]%v_tb   
   )   
   set l=%@index[%v_tb,RAMDISK]   
   iff %l ge 0 then   
     set v_rd=%@substr[cdefg,%@eval[4-%l/11],1]:   
   else   
     set v_rd=::   
   endiff   
   ...............................................................   
      
   try this in a dos shell  ,-)   
      
   addtl. note: config.sys loads 4dos.com with a 4dos.ini reference   
   so completely replaces command.com
