I am somewhat new to data driven formatting but sort of winging it. I have defined a format based on modified proc univariate output. The number of levels in the format is later used to select the number of intermediate colors in a gradient created with the color select macro. Is there a way to select the number of levels in a user defined format into a macro variable? I would like this to remain flexible so I would prefer to pull from the meta-data rather than manually count the number of levels defined (as is done now with the 10 argument in color-scale). I checked the formats dictionary table and there does not appear to be a variable corresponding to the number of levels in the format. Snippet of code below, thanks!
PROC FORMAT; VALUE RANKS 0="0" 1="1" &&VAL_&H.-HIGH ="More than &&VAL_&H." %MACRO MAKE_F (HOWMANY); %DO I=1 %TO &HOWMANY.; %LET K=%EVAL(&I.+1); &&VAL_&I. - %EVAL(&&VAL_&K.-1)="&&VAL_&I. TO %EVAL(&&VAL_&K.-1)" %END; %MEND MAKE_F; %MAKE_F (%EVAL(&H.-1)); RUN; %INCLUDE "&PATH.\PROGRAMS\MACRO\COLOR_SCALE.SAS"; %COLORSCALE(AFD5E8,,CA5B5C, 10, ANNO);
My first idea: write the format to a CNTLOUT= dataset and do a COUNT(*) on it.

Thank you, Kurt. That worked well. I was not aware of that function.
