Yes, what you report is true. It has to do with the RTF style being different than modern styles such as the HTML styles. What happens is When there are two curves, the plot uses the GRAPHFIT and GRAPHFIT2 attributes for the curves. In an HTML style, GRAPHFIT and GRAPHFIT2 have different colors. But in the RTF style, the colors are similar, but one curve is drawn by using a dashed line. Since you have explicitly set PATTERN=SOLID, the two curves look the same in RTF. When there are more than two curves, the procedure uses the GRAPHDATA1, GRAPHDATA2, etc, attributes, which give the curves different colors. There are two workaround. You could delete the PATTERN=SOLID option, but I am assuming you don't want to do this. The second workaround is to modify your macro loop to explicitly use the GRAPHDATA family of attributes, like this: proc sgplot data=graph CYCLEATTRS; %do r=1 %to &n; density &endpoint&r / type=kernel freq=frequency name="&r" legendlabel="&&class&r (n=&&count&r)" lineattrs=GraphData&r.(pattern=solid thickness=2); %end; keylegend / valueattrs=(Size=7); yaxis label='Density'; run; ...

First, turn on NOTEs with OPTIONS NOTES. This will let you know when certain events happen. For example, you should get the notes NOTE: Redefining existing module FFSS_CLASSIFY. NOTE: Module FFSS_CLASSIFY defined. I'm confused by your written statement: The second one has 6 parameters and one error: the "required argument is missing".  I don't see that error in the log, so I don't know what statement is executing when you see it. Please upload the SAS log(s) associated with the errors you are seeing. What version of SAS are you running? Insert %put &=SYSVLONG; into your program so that the result appears in the log. Without seeing all you code and knowing the order in which you are running various programs, it is hard to guess what is happening. My suspicion is that the one of the stored modules is calling ffss_classify with the old syntax. But that error should only appear if the ffss_classify is called or if a second function that calls ffss_classify is being stored. You are claiming that neither of these things are happening, so I am stumped. Try to provide a reproducible example that we can run on our system. ... View more

For a general implementation of the GEV in Base SAS (using PROC FCMP and the DATA step), see the article Implement the generalized extreme value distribution in SAS - The DO Loop which includes functions for the CDF, PDF, quantiles, and random variates.   > I would appreciate it if you could post the codes for pasting the data step for calculating the CDF of GEV into an proc IML module that we call for each value of simulated x data from uniform distribution.   OK. Here it is. See the article for additional IML modules that compute the CDF, PDF, quantile function, and random variates.   /* compute CDF in an IML function */ proc iml; /* this function takes a single scalar value (x) and returns the CDF(x) for the GEV(mu, sigma, xi) distribution */ start GEV_CDF(x, mu, sigma, xi); if sigma <= 0 then return(.); z = (x-mu)/sigma; if xi=0 then CDF = exp(-exp(-z)); else if xi^=0 & xi*z > -1 then CDF = exp(-(1 + xi*z)##(-1/xi)); else if xi > 0 & z <= -1/xi then CDF = 0; else if xi < 0 & z >= 1/abs(xi) then CDF = 1; else CDF = .; return( CDF ); finish; /* set the parameters */ mu = 10; sigma = 2; xi = 0.5; /* compute the CDF function on [0,25] */ x = T(do(0,25,0.25)); CDF = j(nrow(x),1); do i = 1 to nrow(x); CDF[i] = GEV_CDF(x[i], mu, sigma, xi); end; /* visualize the CDF function */ title "CDF for GEV Distribution"; call series(x, CDF) grid={x y};   ...
