JMP adding characters to string?

Hi all,

I had some code that extracted some numbers into variables, and then I put them together in a string.

xlocation = dt1:Die_X[x];

ylocation = dt1:Die_Y[x];

site = dt1:Site[x];

deviceName = "x="||char(xlocation)||" y="||char(ylocation)||" Site"||char(site);

It would output something like this: x= 8 y=2 Site2

But now it outputs this: x=[8] y=[2] Site[2]

I am not sure what I changed. The columns in the data table where I am extracting the variables are Numeric columns.

Does anyone have any ideas why this might be happening? Also, I am having trouble finding an example of how to use the remove from character function.

Something like this? xlocation = Remove From(xlocation, [)?

What's the value of x? It seems that it's a list or matrix of numbers, which is then returning a matrix back to xlocation, ylocation and site.

Might have to insert logic to test x. If it's a matrix extract the first value and use that.

a = [1];

b = char(a);

print(b);

"[1]"

Is the column a JMP 12 expression column holding a matrix?

Here's a debugging idea that might shed some insight. The type() function will tell you the data type of the value in a JSL variable.

x=42;

show(x,type(x),char(x));

x=[3.14];

show(x,type(x),char(x));

x = 42;

Type(x) = "Number";

Char(x) = "42";

x = [3.14];

Type(x) = "Matrix";

Char(x) = "[3.14]";

Thanks PMroz and Craige,

It was a matrix. No idea why it suddenly changed to a matrix though.
