CASE Integrators has built up a huge library of useful field edits which speed up programming considerably.  Although Telon was built long before O-O became a popular concept, it's hard to think of a better example of  'build once - use everywhere'.  We do not have time or space to describe them all, but here are two:

Text Processing

As more users are familiar with PCs, they are more likely to demand the ability to type in lines of text and have it rearranged legibly by the computer: also to edit it later.  Our TEXTFLOW field edit accomplishes this as well as we believe a 3270 possibly can.  It does line wrapping, text insertion, and everything.  PC word processors can obviously do more, but this is a huge improvement over inserting a word in the middle of a paragraph by deleting the last word on the end of each line and adding it to the beginning of the next.

DB2 Date Processing

For reasons best known to itself, CA has yet to release a DB2 date routine.  Building one is complicated by the fact that DB2 presents dates in various formats, by Y2K considerations, etc.  Our routine handles any DB2 date presentation format, and any screen-field length from 6 through 11.  Odd lengths imply that the month is alpha, on output a length of 8 or above displays the century, on input the number of non-blank characters rather than the field length is used to determine the format, etc.  Also the routine allows the date to be displayed on the screen as three fields instead of one.  All this requires no more application programmer effort than using the CA-supplied DATE, and indeed less, since the programmer will get results without exact field lengths.
