290 Data Tables Chapter 9
Row State Operators
choices are 0, 1, 2, ..., 84; 0–15 for the basic colors, 16–31 for dark shades of the same colors, 32–47 for
light shades, 48–63 for very dark shades, 64–79 for very light shades, and 80–84 for shades of gray.
Values outside the range 0 to 84 are undefined. For best results, use Modulo or other operators to enforce
valid values.
Missing values result in no row state.
An Overview of Row State Operators
From JSL, you can get or set row states directly using the Row State operator. You can get or set the state
for row n with Row State(n). If you do not supply an argument, you set or get the current row. To work
with all rows, either use a For Each Row loop or else work with formula columns. Continuing the example
with the data table just created:
rowstate(1); // returns row state for row 1
Color State(1)
row()=8;rowstate(); // returns row state for current (8th) row
Color State(8)
for each row(print(rowstate()));
Color State(1)
Color State(2)
Color State(3)
Color State(4)
Color State(5)
Color State(6)
Color State(7)
Color State(8)
Color State(9)
Color State(10)
To get a row state and store it in a global, place Row State() on the right side of an assignment:
::x=rowstate(1); // puts the row state of row 1 in x, a global
row()=8;::x=rowstate(); // puts the row state of the 8th row in x
show(x);
x = Color State(8)
// put row states in rscol, a row state column
