JSL: How to set a single row across multiple columns to a single value?

SDF1 — Tue, 10 Jun 2025 16:42:02 GMT

Hello JSL specialist,

Wondering if there is an elegant (simple) way to set a single row across all columns to a single value.

I know I can do a For loop, and the For Each Row isn't quite what I'm after either.

I'm almost looking for an analogous command, like For Each Column or something like that. Perhaps there doesn't exist a command that can set a single row across all columns to a given value, but I'm hoping to find a more elegant way of doing this than brute force with a For loop.

Thanks!,

I found the answer I was looking for thanks to @Craige_Hales' post here: https://community.jmp.com/t5/Uncharted/Data-table-subscripting/ba-p/21013 about table subscripting.

There is an elegant way: dt[row, column]=x;

If you want all of row 1 to be a value, you use: dt[1,0] = x. Similarly for a column and so forth.

This is exactly the elegant way I was looking for.

Hope this can help some others as well.
