7.12.2 CHANGE Comments/Warnings

• When changing multiple variables simultaneously to an expression, the position of the field will affect the result as shown in examples A and B.

Define Field(#STD_NUMSV) Reffld(#STD_NUM)

     Example A: #std_num gets value 5 and #std_numsv gets value 6

     Change Field(#STD_NUM) To(4)
     Change Field(#STD_NUM #STD_NUMSV) To('#std_num + 1')

     Example B: #std_num gets value 5 and #std_numsv gets value 5

     Change Field(#STD_NUM) To(4)

     Change Field(#STD_NUMSV #STD_NUM) To('#std_num + 1')

Using quotes

• In RDML functions, a literal whose first character looks like a number (begins with plus, minus, decimal point, or a digit), must be triple quoted using three single quotes. For example:

     CHANGE FIELD(#ADDRESS1) TO('''1 Mount ST''')

• In RDMLX code:

• • The literal needs to be enclosed in double-quote characters:

     CHANGE FIELD(#ADDRESS1) TO("1 Mount ST")

• • When assigning the value, the literal can be in either single or double quotes:

     #ADDRESS1 := '1 Mount ST'

or

     #ADDRESS1 := "1 Mount ST"
