past colHello, I would like to copy only the first 8 characters of the rows of the column Material Number in the column 2.

ScriptingRe: past colSee the character string functions in the JMP documentation or Scripting Index:

The Left( string, number of characters) should work for this case.
Re: past colAnother way (if you need the first part of the string befor the "-") would be to use the word function,
in a first step you can let JMP create the formula,

and then you need to set the word separating character to "-".
