ISIN

ISIN

Name


    ISIN

Purpose


    This function will tell you whether or not a token is contained in an
    array.

Category


    Array

Calling Sequence


    result = IsIn( Data, Token )

Inputs


    Data: The input data array (any type).
    Token: The item to search for in array (the same type as data). This can
        be a vector of length N_TOKEN.

Keywords


    NO_CASE: If this keyword is set all inputs are converted to uppercase
        before the comparison is made.

Output


    Result: (0,1) if (not found, found). If Token is a vector, then result
        is a vector of length N_TOKEN with each element being the result for
        the corresponding element in Token.

Uses


    var_type.pro

Procedure


    This function uses the Where command to identify all occurences of the
    token in the data array and returns a 1 if at least on was found.

Example


    data = findgen( 10, 10 )
    if ( IsIn( data, 10 ) ) then Print, '10 is in the data'
