try
%put %sysget(sasroot) ;

The environment variable name is case sensitive on Unix platforms.
Review all environment variable names and values in data step( except
on EG with default NOXCMD option)

(untested)
data evars( compress= yes ) ;
   length name $32 value $200 ;
   filename pevars pipe 'set ' lrecl= 2000 ;
   infile pevars truncover dlm='='  col= col;
   input name @;
   if name ne ' ' ;
   value = substr(_infile_, col );
   put name= / value /;
run;
