no what you are trying is not possible, however you can use an array if it are a lot of bools.
like test[1]:=true;
etc.
but you have to make it in advance as it is impossible to change the variable list in a running program

however i/o must be in global list with all %QX0.0 in writing.
(you can automate this with a textmaker.

Actually I want to use

Test1:bool
Test2:bool
Test3:bool

for i=1 t0 3
test:=concat('Test'+int_to_string('i'))
end_for

i do not want to use if else statement

its compiling yet am not seeing any output

NO, you can not make variablenames inside your code, as the code is compiled all this info is lost again.

however you can make a automatic declarationtable (in any textmaker like NPP).
sorry for the misunderstanding.

what are you trying to do?
look for data types here you can make types and structures

Is there no way to convert a string to the desired variable name we declare no matter what sort of declaration it is

for eg: r_codesys:real;
b_codesys:bool;
i_codesys:int;

string_to_real('r_codesys')
string_to_bool('b_codesys')
string_to_int('i_codesys')

is not the above things possible?

Are need to write my own code to make it work like this?

so
check :STRING(30):='23.45';
check2:REAL;

use oscat.de FLOAT_TO_REAL function
check2:=FLOAT_TO_REAL(check);
however no output is in real, but you can use REAL_TO_WORD.

in boolean it is simpler
IF (check= '23.45') THEN heateron:=TRUE;END_IF

well then for bool

eg heateron: bool(This boolean not from hardware)

check:=concat('heater'+'on')
check2:=string_to_real(check2);

Is it possible?

you have a WORD not a REAL coming from the inputcard.
there are no direct inputs with real.
conversion is possible with word_to_real (value is 10 times the measured value)
so your setpoint is a real, not a string.
and you can not have 1 var (check2) double declared

am trying to convert string to an Io

eg heatertemperature %iw23 real

check:=concat('heater'+'temperarture')
check2:=string_to_real(check2);

Is it possible?
