FIELDTEXT mystery

[Ohmes, Matt]

Yep, classic Fieldtext problem.  The DISPLAY FIELD_2 is screwing you up.
The DISPLAY verb takes the contents of FIELD_2 from the record buffer,
PLACES IT IN FIELDTEXT! and displays it on the screen. This, of course,
replaces whatever value was already in FIELDTEXT (E, O, or C in this case).

Either save the value that's in FIELDTEXT into a temporay before you call
the DISPLAY, then restore it, or drop the DISPLAY statement completely.
FIELD_2 will probably get displayed in it's own time anyway.

Good luck,
Matt

Afternoon All

I have a procedure which tests the value of FIELDTEXT for one field, and
changes the contents of a second field, based on the given value.
However, somewhere after EDIT and before OUTPUT, the FIELDTEXT for the
first field assumes the ASCII(value) of the second field:

PROCEDURE EDIT     FIELD_1
BEGIN
    IF         FIELDTEXT = "E"
          THEN LET FIELD_2 = 2
       ELSE IF FIELDTEXT = "O"
          THEN LET FIELD_2 = 1
       ELSE IF FIELDTEXT = "C"
          THEN LET FIELD_2 = 6
   DISPLAY FIELD_2
END

Any idea how I can stop this?

Regards
