Currently available versions of Classic 4GL do not have this ability without needing considerable programming effort (pace Dennis and Art). However, Dynamic 4GL has a function dialog.setcurrline() which allows you to place a given line of the program array on a given line of the screen array. In Classic 4GL release 7.30, this facility will be back-ported from Dynamic 4GL. There are also due to be a bunch of other useful additions to INPUT ARRAY in particular -- you can check the SEIUG web site (http://www.iiug.org/~seiug/, and the trailing slash is reputedly significant) for more info. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.60 -- see http://www.perl.com/CPAN #include <disclaimer.h>
