Support : Dialog Search Aids : Successful Searching : EXECUTE and EXECUTE STEPS

EXECUTE

EXECUTE STEPS

Both EXECUTE and EXECUTE STEPS are used to run SearchSaves that have been stored online with SAVE, SAVE TEMP, SAVE ALERT, RANK, and MAP. Enter either command followed by the serial number or name of the stored strategy.

If you enter either EXECUTE or EXECUTE STEPS without a SearchSave serial number or name, Dialog will automatically execute the most recently stored search from the current search session. If you do not have a saved search in your current search session, you will be prompted to enter a serial number or name.

EXECUTE runs your search and creates a single set. EXECUTE STEPS runs your search and creates a set for each command line stored.

EXECUTE STEPS is preferred because it is the more versatile of the two commands. By creating a set for each command line, EXECUTE STEPS creates the same set numbers as the original search, enabling you to SAVE the new strategy.

While EXECUTE will also run a search correctly, it can be restrictive. Intermediate steps within the SearchSave cannot be used in later search statements, because only one set number is created. And if additional search statements are added after the search is EXECUTEd, and the new strategy is then saved, this SearchSave will not EXECUTE properly because the set numbering in the old SearchSave is incompatible with the set numbering in the new one.

EXECUTE is recommended when EXECUTE STEPS would cause the SearchSave to exceed the maximum number of 999 sets per search.

A SearchSave may contain any of the commands listed below that you entered while creating the search strategy:

A RECALL of the SearchSave will display these command lines, but only the set-producing commands and SET commands are processed when you run the SearchSave online using EXECUTE or EXECUTE STEPS.

• EXECUTE assigns only one final set number:
