Re: Delete all rows except row 1.

Here is a simple solution.....all messages and functions used are documented in both the Scripting Guide and the Scripting Index

names default to here( 1 );
dt = Open( "$SAMPLE_DATA\Big Class.JMP" );

dt << select where( Row() > 1 );
dt << delete rows;

How would you do it interactively? Translate those steps into JSL, as Jim did.
