PROC FREQ determines the variable levels from the formatted variable values, as described in the section Grouping with Formats. See the section Number of Variable Levels Table for details. NLEVELSĭisplays the "Number of Variable Levels" table, which provides the number of levels for each variable named in the TABLES statements. See the CALENDAR, PLOT, and TABULATE procedures in the Base SAS Procedures Guide for more information about form characters. For information about which hexadecimal codes to use for which characters, see the documentation for your hardware. If you use hexadecimal characters, you must put an x after the closing quote. You can use any character in formchar-string, including hexadecimal characters. Specifying all blanks for formchar-string produces crosstabulation tables with no outlines or dividers-for example, FORMCHAR(1,2,7)=' '. Therefore, the proper specification for PROC FREQ is FORMCHAR(1,2,7)= ' formchar-string'. The FORMCHAR= option can specify 20 different SAS formatting characters used to display output however, PROC FREQ uses only the first, second, and seventh formatting characters. Intersections of vertical and horizontal separators Table 35.5 Formatting Characters Used by PROC FREQ Table 35.5 summarizes the formatting characters used by PROC FREQ. If you do not specify the FORMCHAR= option, PROC FREQ uses FORMCHAR(1,2,7)='|-+' by default. The characters are used to draw the vertical separators (1), the horizontal separators (2), and the vertical-horizontal intersections (7). The formchar-string should be three characters long. If you omit the DATA= option, the procedure uses the most recently created SAS data set.ĭefines the characters to be used for constructing the outlines and dividers for the cells of crosstabulation table displays. Names the SAS data set to be analyzed by PROC FREQ. The COMPRESS option is not valid with the PAGE option. By default, the next one-way table begins on the current page only if the entire table fits on that page. Begins display of the next one-way frequency table on the same page as the preceding one-way table if there is enough space to begin the table.
