Updating 2.x scripts

Changes in the script language compared to its 2.x version are minimal, but it is required to change bits and pieces of a script file in order to have it working in the 3.x series:

• Every variable must start with the character “$”. Put $ at the beginning of every variable. See the example below.

  # Variables:
  #
  # 2.x:
  myuser="joe"
  mypass="1234"
  myserver="ftp.host.com"
  myresult=OPENHOST(myserver,myuser,mypass)
   
  # 3.x
  $myuser="joe"
  $mypass="1234"
  $myserver="ftp.host.com"
  $myresult=OPENHOST($myserver,$myuser,$mypass)

• Every label must start with the character “:”. Put : at the beginning of every label. See the example below.

  # Labels:
  #
  # 2.x
  :mylabel
  GOTO mylabel
   
  # 3.x
  :mylabel
  GOTO :mylabel

• The commands ISEQUAL, NOT, ADD and CONCAT are no longer supported. You have to replace them with their corresponding symbol. See the example below:

  # ADD, NOT, ISEQUAL and CONCAT
  #
  # 2.x
  num=ADD(num,3)
   
  IF(NOT(ISEQUAL(result,"OK")))
  PRINT("operation failed")
  END IF
   
  IF(ISEQUAL(result,"12451"))
  PRINT("Access error")
  END IF
   
  mymessage=CONCAT("hello ",name)
  PRINT(mymessage)
   
  # 3.x
  $num=$num+3
   
  IF($result!="OK")
  PRINT("operation failed")
  END IF
   
  IF($result==12451)
  PRINT("Access error")
  END IF
   
  $mymessage="hello ".$name
  PRINT($mymessage)

• The command LIST is no longer supported. Use GETLIST and FOREACH instead. See the example below:

  # ADD, NOT, ISEQUAL and CONCAT
  #
  # 2.x
  num=ADD(num,3)
   
  IF(NOT(ISEQUAL(result,"OK")))
  PRINT("operation failed")
  END IF
   
  IF(ISEQUAL(result,"12451"))
  PRINT("Access error")
  END IF
   
  mymessage=CONCAT("hello ",name)
  PRINT(mymessage)
   
  # 3.x
  $num=$num+3
   
  IF($result!="OK")
  PRINT("operation failed")
  END IF
   
  IF($result==12451)
  PRINT("Access error")
  END IF
   
  $mymessage="hello ".$name
  PRINT($mymessage)

• The command SETSSL has been renamed to SETPROTOCOL. The syntax and parameters are the same.
• The command QUOTE is no longer used. Use simple quotes (‘) in the

  # ScriptFTP 2.x:
  # This command produces the external command:
  # copy "my file.zip" C:\destination
  EXEC(CONCAT("copy ",QUOTE,"my file.zip",QUOTE," C:\destination"))
   
  # ScriptFTP 3.x:
   
  # This command produces the external command:
  # copy "my file.zip" C:\destination
  EXEC('copy "my file.zip" C:\destination')
