Example
// Modify a row in a Looper control
LooperModifyLine(LOOP_Looper1, Subscript, ProductName, ProductCode)
// Modifies a value in the Looper control at position 12
LooperModifyLine(LOOP_Looper1, 12, LastName, FirstName, PhoneNum, FaxNum)
Syntax
LooperModifyLine(<Looper control> [, <Subscript> [, <Value 1> [, <Value N>]]])
<Looper control>: Control name
Name of Looper control to use.
If this parameter is equal to an empty string (""), the modification will be performed in the current Looper control.
<Subscript>: Optional integer
Subscript of row to modify.
  • If this parameter is not specified, the modification will be performed on the current element.
  • A WLanguage error is displayed if <Subscript> is greater than the number of rows.
<Value 1>: Type of associated attribute (optional)
Value of the 1st attribute of the row that must be modified in the specified Looper control.
The different values must be specified in the order of attributes (description window of Looper control).
If none of these parameters is specified, LooperModifyLine assigns an empty string ("") or 0.
<Value N>: Type of associated attribute (optional)
Value of the Nth attribute of the row that must be modified in the specified Looper control.
The different values must be specified in the order of attributes (description window of Looper control).
If none of these parameters is specified, LooperModifyLine assigns an empty string ("") or 0.
Remarks

Use conditions

LooperModifyLine can be used on a browsing or memory Looper control.

Characteristics of the row

If a value corresponds to the result of a calculation, the numeric expression must be enclosed in brackets. For example:
LooperModifyLine(LOOP_CalcLooper, 5, (53+29), (83-21))

Sort

If LooperModifyLine modifies a sort attribute of the current Looper control, the sort on this attribute will be canceled.

Modifying a Looper control without attributes

To modify a Looper control without attributes, we recommend you directly modify the value of the relevant controls.
For example:
// Modify the value of controls
// in "LOOP_Looper1" for row 23
LOOP_Looper1[23].LastNameControl = "Hobbes"
LOOP_Looper1[23].FirstNameControl = "Samantha"
