Code:
IF instr(@IPADDRESS0,"192.168.  5")
   IF @userid = 'adm-jack' or @userid = 'jack' 
      USE E: "\\workstat\c$$" /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE F: '\\workstat\d$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE G: '\\workstat\e$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE H: '\\workstat\f$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE I: '\\workstat\g$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE J: '\\workstat\h$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE K: '\\workstat\i$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE L: '\\workstat\l$$' /user:@WkSta\adm-jack /password:something
      ? 'Error '+@ERROR+' - '+@SERROR
      USE M: '\\workstat\m$$' /user:@WkSta\adm-jack /password:something 
      ? 'Error '+@ERROR+' - '+@SERROR
