Hello Team,

Can anyone tell me/ give a link to understand the scan time/ execution sequence of difference instructions in SCL. E.g IF,FOR,WHILE,DO WHILE etc.

For e.g)

if Start then
for n:=0 to 10 then
Case n of
Case 0: statement1;
Case 1: statement2;
Case 2..10 : Statement3;
end_case
end_for
End_if

The case statements will execute properly in above instruction or it will make impact on "for" instruction execution.

Anything mistake happened to my question or miss understand from my side please guide..

Regards,
PM
