The default number of commands is 20, but this can be changed by specifying a number in the .L command: .L5 05 04 03 02 01 sort xrates CT XRATES 15346 sort irates SORT IRATES DATE OVERNIGHT DAYS90 YRS10 SORT XRATES DATE USD GBP AUD JPY EUR To execute a command that is already on the command stack, use .Xn where n is the number of the command. To repeat the sort on the dictionary of the IRATES file (command number 2), we would type .X2 .x2 SORT IRATES DATE OVERNIGHT DAYS90 YRS10 IRATES.... Date.......

This duplicates the existing command, and pushes all previous commands down the stack. In this case, we now have the command: SORT IRATES DATE OVERNIGHT DAYS90 YRS10 at both position 1 and position 3 on the stack. The .C command changes the text in a command. While we could change the text in any command on the stack, it is usually most convenient to operate on the first command. In this case, we may need to retrieve ( .R) an earlier command from the stack. .R2 02 SORT XRATES DATE USD GBP AUD JPY EUR .C/AUD/CNY 01 SORT XRATES DATE USD GBP CNY JPY EUR This sequence has retrieved the 2nd command from the stack, and then changed ‘AUD’ to ‘CNY’ in the list of currencies to display. We could then execute this new command simply by typing .X .X SORT XRATES DATE USD GBP CNY JPY EUR XRATES.... Date........
