Nested for loop problem

Jay

Hi, I am testing a nested for loop.

 

col loop will create new columns

row loop will write in data for each row.

 

The inner row loop seems has problem, it created 1st col, but that is all.

 

====================

colNames=list();
colNames[1]="A";
colNames[2]="B";
colNames[3]="C";

dt = New Table("new");
Current Data Table(dt);

for (col=1,col<=3,col++,
 
    dt<<NewColumn(colNames[col]);
 
    for(row=1,row<=4,row++,    
    //write data into eachrow
    );

);

You need to open the JMP log so you will see the errors.  I assumed the code you showed was psudo code, just showing the structure of how you wanted the code to work.  In JSL, you can not have a For loop without any arguments.  So I have adjusted the code I returned to you, so it will work

Names default to here(1);
colNames = List();
colNames[1] = "A";
colNames[2] = "B";
colNames[3] = "C";

dt = New Table( "new" );
Current Data Table( dt );

// Add Empty Rows to the Data Table
dt << Add Rows( 4 );

For( col = 1, col <= 3, col++, 
 
	dt << New Column( colNames[col] );
 
	For( row = 1, row <= 4, row++,    
    // Or you could conditionally add rows here
    // If( Col == 1, dt << Add Rows( 1 ) );
    column(dt,ColNames[col])[row]=1;
	);

);
