I played a bit with v4 apps today (on Elementary linux distro) and most things worked as expected. I used: EpiData Manager: (2017/01/01 - 16:08:45) Program Version: 4.0.0.94 [RC1] r1364 Core version: 4.0.0.0 r1337 FPC Version: 3.0.0 Platform: x86_64-Linux

EpiData Analysis: (2017/01/01 - 16:07:11) Program Version: 0.6.0.0 [PROTOTYPE] r? Core version: 2.1.0.0 r1335 FPC Version: 3.0.0 Platform: x86_64-Linux

The only problem encountered so far:

Manager & EntryClient: the browse columns get larger when repeatedly clicking on the button to show values/labels. This is not the case with Analysis.

Analysis: thanks for the short intro file that shows what is available in this version. I was annoyed that I got errors when there was no data because of select, but played with the syntax and did this as a workaround. I'm showing this just because the syntax works quite well.

new global i i; for i := 1 to 3 do begin select gender = i count; if $count>0 then freq age; end;

Having FOR and BEGIN blocks means we can use some sophisticated command syntax.
