sr.tag＝string(sr2-200)
if?sr2＞(zjs1+201)then
sr.visible＝false
end?if
sr.x＝s1+ss*(sr2-200-1)
else
If sr2＞400and sr2＜=600 then//second row RichTextEdit the control, the anxious state that stops of expression support
sr.tag＝string(sr2-400)
if?sr2＞(zjsl+401)then
sr.visible＝false
end?if
sr.x＝s1+ss*(sr2-400-1)
end?if
end?if
end?if
end CHOOSE
next
