comparing two boolaen variables and insert new variable with true variable

hello harikiran thanks for reply

for "no" variable and "no1" variable some time its coming as true and some times its coming as false but we dont know perfect when it comes true and false .

buy comparing both variables i want to insert third variable "no12" as true variable when both the variables are different.

but in your example it saying "no" as true in one way and onother way "no" as false
so you easily assign it ..but my scenario is we dont know when it come true and when it come false.

i already wrote like this example but it shows length and it is not correct because if i have 30 fields then it go more and more
here

no as boolean
no1 also boolean
no12 as text
no123 aslo text


IF no<>no1 THEN BEGIN
IF no THEN
no12:='No'
ELSE
IF no1 THEN
no123:='No';
END;
IF description<>description1 then BEGIN
IF description THEN
description12:='Description'
ELSE
IF description1 THEN
description123:='Description';
END;
message(%1%2%3%4, no12,no123,description12,description123......)
here i want to show only true variables when both the variables are different .....this one i want to achieve...please say any other method

Thanks
DJ
