Solved... it is where the end if's were placed!
local nM
on mouseUp
startProcess
end mouseUp
command startProcess
put fld dbPathList into nM
open process nM for update
set the cRunning of this card to true
readloop
end startProcess
command readloop
if the the cRunning of this card then
read from process nM until empty
if it is not empty then
put it & cr after fld mergeOut
put the number of lines of fld mergeOut * 16 into sPlace
set the vscroll of fld mergeOut to sPlace
end if
if it contains "dblink disconnecting" then
set the cRunning of this card to false
close process nM
exit to top
end if
end if
send "readloop" to me in 1 tick
end readloop
