     assuming the calc is located in /usr/local/bin/calc, the first
     line of a calc script would be:
 
-	#!/usr/local/bin/calc -f
-	...
+        #!/usr/local/bin/calc -f

     then argv(0) will refer to the filename of the script.
 
     As it is common to use -q in a calc script, and using that same
     /usr/local/bin/calc location:
 
-	#!/usr/local/bin/calc -q -f
-	...
+        #!/usr/local/bin/calc -q -f

     and again, argv(0) will refer to the filename of the script.

     However, if calc is invoked with -s, all non-dashed options will
     be left as unevaluated strings.  Thus:
 
-	calc -i 2+2
+        calc -i 2+2
 
     will cause calc to print 4 and enter interactive mode.  In this case
     argv() will return 1.
 
     On the other hand:
 
-	calc -i -s 2+2
+        calc -i -s 2+2
 
     will cause calc to interactive mode.  The argv() builtin will return 2
     and argv(1) will return the string "2+2".
