the instrument (L4450A) to execute the sequence named “TOTAL_1”
when an alarm (count of 50) is reported on Alarm 1. The Monitor mode
is used to evaluate alarm conditions on the selected channel.
ROUT:SEQ:DEF TOTAL_1,"SYST:DEL 1000"
CALC:LIM:UPP 10.25,(@1301)

Deleting Sequences
You can delete sequences to free up space in memory previously
allocated for the sequence.
If you attempt to delete a sequence while it is executing, an error
will be generated. To abort a sequence execution, use the
ROUTe:SEQuence:ABORt command or a Device Clear.
Deleting a sequence will remove its association with an alarm if used
(see
“Executing a Sequence on an Alarm Condition" on page 94 for
more information).
The following command deletes the sequence named “TOTAL_1”.
ROUT:SEQ:DEL TOTAL_1
The following command deletes all sequences from memory.
ROUT:SEQ:DEL:ALL
Reading the List of Stored Sequences
You can read the names of all sequences currently stored in memory.
When stored in memory, the user- defined sequence names are
converted to all uppercase letters. For example when stored, “Total_1”
is converted to “TOTAL_1”.
Up to 500 unique sequences can be stored in non- volatile memory.
Each sequence is limited to 1024 bytes.
The following command returns a comma- separated list of sequence
names currently stored.
ROUT:SEQ:CAT?
The above command returns a string in the form:
