- "SELECT RECORDS ALPHA HELP"
-
- "When records are selected by alpha comparison a data segment may be"
- "targeted or all alphanumeric, or string, fields may be searched. The"
- "value as comparitor is entered from the keyboard. The purpose of"
- "record selection, whether alpha or numeric comparison is employed, is"
- "to dis-continue processing the records not conforming to the parameter"
- "specified; to reject them from the current group."
-
- "Full-screen menus guide you through the setup of the EXCLUSIVE SORT"
- "about to be done. First you are asked if you wish to use one segment,"
- "or all fields holding alpha data as the target of the record selection"
- "process. If you have done previous record selects, and have not acces-"
- "sed the counters, you may opt to sort the survivors of the last sort,"
- "deleting non-survivors from the current group, or to sort all records,"
- "adding survivors to the current group, and ending up with a group of"
- "records meeting one or more of the specified criterion."
-
- "Then you will enter the search string, or the data you're looking for."
- "Finally you choose the direction of the sort; whether the survivors"
- "will or will not contain the search string."
-
- "Before executing the sort, the program re-displays your input. If you"
- "have erred you can re-select the parameters, or abort the sort."
-
- "Case and spacing may be optionally ignored. If you opt to ignore case"
- "and spacing entering `fredjones' would include records containing FRED"
- "JONES, Fred Jones and Fred JONES in the survivor group. If you opt to"
- "exactly match case and spacing none of the above examples would be put"
- "into the survivor group; only those records containing an exact match"
- "would be seen by the program as survivors."
-
- "You may also choose matching on strict equality or instring searching."
- "If you opt for an instring search and enter FRED as your search string"
- "then all records containing the word fred will be survivors. That in-"
- "cludes Fred Jones, Fred Davis, and Joe Fred, too."
-
- "If you opt for strict equality then only those records containing the"
- "five letters FRED will be survivors. Case and spacing can still be ig-"
- "nored, if you wish."
-
- "When you return to browse the records not containing the search string"
- "will not be displayed, printed, found, totaled-averaged, etc. Until"
- "you press F11 they might as well not be in the file."
-
- "If you targeted a single segment for the search it will be displayed"
- "in the secondary screen area so that you can visually verify the res-"
- "ults of your sort. To turn it off Press F18 and then press 3."
-
- "You may do as many record selects as necessary to define your group."
-
- "At times you may find that this and other functions have not done what"
- "you thought they would. The only reason you will, by paying attention,"
- "be able to catch errors as they happen is the one-step operation. If"
- "you selected on all your criterion at once you would, of necessity, be"
- "deprived of your opportunity to verify what happened by BROWSING the"
- "survivors between operations."
-
- "Wouldn't it be FASTER if we did it all in ONE PASS through the file?"
-
- "Two factors govern the speed of the select records operations: number"
- "of records to be processed and number of tests to be done. Each select"
- "causes the next one to have fewer records to deal with, and with the"
- "advantage of a single test being done the difference in speed is not"
- "as great as you might imagine."
-
- "An appropriate response to incorrect data is a MISTAKE. The production"
- "of mistakes, no matter how rapid, has no facility. If you use the"
- "tools provided by THE DATAMAGE your results will be correct. ACCURACY"
- "needs no excuses."
