Use this if you have one or two items to delete or will be running repeatedly with different deletion and selection patterns, otherwise use IDFILE=.

 

If your system is interactive, items to be deleted or selected can be entered interactively by setting IDELQU=Y. If you specify this, you will be asked if you want to delete any items. If you respond "yes", it will ask if you want to read these deleted items from a file; if you answer "yes" it will ask for the file name and process that file in the same manner as if IDFILE= had been specified. If you answer "no", you will be asked to enter the sequence number or numbers of items to be deleted or selected one line at a time, following the rules specified for IDFILE=. When you are finished, enter a zero.

 

Example: You are doing a number of analyses, deleting a few, but different, items each analysis. You don't want to create a lot of small delete files, but rather just enter the numbers directly into the program using:

  NI=60

  ITEM1=30

  IDELQU=Y

  &END

 

You want to delete items 23 and 50 through 59.

WINSTEPS asks you:

DO YOU WANT TO DELETE ANY ITEMS? 

respond YES(Enter)

DO YOU WISH TO READ THE DELETED ITEMS FROM A FILE? 

respond NO(Enter)

INPUT ITEM TO DELETE (0 TO END): 

respond 23(Enter) (the first item to be deleted)

INPUT ITEM TO DELETE (0 TO END): 50-59(Enter)

INPUT ITEM TO DELETE (0 TO END): 0(Enter) (to end deletion)

 

If you make a mistake, it is simple to start again, reinstate all items with

INPUT ITEM TO DELETE (0 TO END): +1-999(Enter)

where 999 is the length of your test or more, and start selection again.
