search terms: kloc == one thousand lines of code

the problem is what is a 'line of code'?

do you want to count just semicolons?

and does it count if a line has both
a statement
and a comment ?

we have (at least) three types of comments in SAS:
* statement;
/* comment */
%* macro comment;

asterick statements are easy: they occur at statement boundaries

slash asterisk comments can cut across anything:
intra- as well as inter-statement comments

and macro comments can appear within SAS statements:

attrib I length = 4 %*integer;
J length = 4 %*integer;
X length = 8 %*real;
;
