In this example, an extraction area is assigned to the variable curLine each time the current
page value has changed.
curPage = steps.currentPage;
for(i=0;i<100;i++) {
if(steps.currentPage > curPage) {
let curLine = data.extract(51, 88, 0, 1, "").trim();
curPage++;
}
}
moveTo()
Moves the position of the pointer in the source data file. This is a method of the steps object
(see "steps" on page421).
moveTo(scope, verticalPosition)
Moves the current position in a text file to verticalPosition where the meaning of
verticalPosition changes according to the value specified for scope.
scope
Number that may be set to: 0 or steps.MOVELINES1 or steps.MOVEDELIMITERS2: next line
with content
verticalPosition
Number. What it represents depends on the value specified for scope.
With the scope set to 0 or steps.MOVELINES, verticalPosition represents the index of the line
to move to from the top of the record.
With the scope set to 1 or steps.MOVEDELIMITERS, verticalPosition represents the index of
the delimiter (as defined in the Input Data settings) to move to from the top of the record.
With the scope set to 2, verticalPosition is not used. The position is moved to the next line after
the current position that contains any text.
