Local variables are declared in a script section this way:

'   ---------------------------------------------
'   Declare Local Variables in a manner similar
'   to these three declaration, but you should
'   consider using more meaningful names if it
'   is important
Variables: AnyNum1, AnyNum2, AnyNum3       TYPE: INTEGER
Variables: AnyFloat1, AnyFloat2, AnyFloat3 TYPE: FLOATING
Variables: AnyText1, AnyText2, AnyText3   TYPE: STRING
Variables: pAnyPrice                       TYPE: PRICE

 

Local variables are not cleared to zero or any other value when they are declared.  Clearing a local variable is the responsibility of the script section in which they are declared and used.  Assigning a value to a local variable is no different than assigning a value to a Blox Permanent variable, a Instrument Permanent Variable.

 

For example, consider these value assignments for the first local variable in the three different local variable declaration types:

'   ---------------------------------------------
'   Assign Some Value to these three variable types
AnyNum1 = 100
AnyFloat1 = 10.01563
AnyText1 = "Order Placed"

 

Local variables are not accessible to other scripts unless they are contained within a Custom Function.  When contained in a Custom Function, all the variables contained within the script section are accessible to script section from which the Custom Function was called.
 

'  MKT is a BPV Instrument TYPE
'  Local declared variables
VARIABLES: iAvgLen, iCount, iLoadOK, x, y Type: Integer
VARIABLES: iCount, instrumentCount       Type: Integer
VARIABLES: fAvgClose                     Type: Price
 
'  Initialize Variables
iAvgLen = 5
iCount = 0
 
' Get the large Stock Portfolio instrument count.
instrumentCount = system.totalInstruments
 
' Loop printing the symbol for each instrument.
For x = 1 TO instrumentCount STEP 1
 
  ' Load this portfolio instrument into context.
  iLoadOK = Mkt.LoadSymbol( x )
 
  ' Print out the file name.
  If iLoadOK = TRUE THEN
    '  Initialize Variables
    iCount = 0
    fAvgClose = 0
 
    '  Sum the Close Prices
    For y = 0 TO iAvgLen - 1
        '  Add Close Prices
        fAvgClose = fAvgClose + Mkt.close
    Next
 
    '  Calculate the Average Close Price
    fAvgClose = (fAvgClose / iAvgLen)
 
    '  Display the Symbol Information Results
    PRINT x, Mkt.symbol, fAvgClose
  ENDIF
Next ' x
