Informix 4gl Version 7.30: INPUT ARRAY
LGN -Abteilung 2- reported that SCROLL ... UP/DOWN BY in INPUT ARRAY no longer moved the current line in Informix 4GL 7.30 on Linux, though it worked in 4.1. Earle Long asked for details and code. Andrew Hamm said he had never seen SCROLL control the current line, that it is transient, and that version 7.3 now does what he wanted from it. No fix was given.

Hello! I use Informix 4gl version 7.30 / Linux 2.2.16. INPUT ARRAY: "SCROLL ... UP/DOWN BY ..." doesn't work! Could someone help me? Thanks!
More explanation than "doesn't work" would be useful along with the source code.

First I have to say that "SCROLL ... UP/DOWN BY ..." worked with the former Informix4gl-Version 4.1. Now (Version 7.30) the current line doesn't move?! Here is an example: INPUT ARRAY da_v0011 WITHOUT DEFAULTS FROM scr_v0011.* ... ON KEY (F5) LET pi_scroll = ARR_COUNT() - ARR_CURR() SCROLL scr_v0011.* UP BY pi_scroll LET pi_arr = ARR_CURR() LET pi_scr = SCR_LINE() DISPLAY da_v0011[pi_arr].* TO scr_v0011[pi_scr].* ...

It would be wonderful to control the current line. But AFAIK it's always done a transient job, and as soon as the INPUT statement goes back to a waiting state (waiting for keyboard input) it reasserts it's positioning and you've wasted your time with the SCROLL. I thought SCROLL was only useful if you are manually managing your own screen array. Perhaps I tested on a defective version? If SCROLL can be used usefully in INPUT ARRAY, I'd like to know about it; 5 years ago please! Version 7.3 now does what I wanted SCROLL to do.
