How will compress if ARMCD length more than 20 character. Please give me answer

Which Compress are you talking about? Libname has a compress option, compress is also a data set options and there is a Data step function compress.

If the data function then you will need to provide actual examples since the purpose of the function is to remove characters. The result is very highly dependent on 1) the starting value and 2) the list of characters supplied to remove. The length doesn't matter too much.

this is my code but i am getting turncation . I want no turncation .I want
one variable contain 200 length not more than 200 and no truncation

DATA temp;
SET text;
length coval coval1 coval2 $200 ;
ovar=coval_t;
if len_t=<200 then coval=substr(coval_t,1,200);
if 200coval=substr(coval_t,1,200);
coval1=substr(coval_t,201,400);
end;
if len_t>400 then do;
coval=substr(coval_t,1,200);
coval1=substr(coval_t,201,400);
coval2=substr(coval_t,401);
end;
keep ovar coval coval1 coval2;
