questions on sas formating issue.

[winecoding]

In the following sas code segment, what do the "lib=sasuser " and "select" mean here? Thanks.

proc format lib=sasuser cntlout = sasuser.fmtdata;
     select $airport;
run;

Hello Winecodeng,

Lib SASUSER is a standard SAS library for user files. It is assigned by default.

Select $airport;
means that information about character format $airport will be output to sasuser.fmtdata dataset.

Sincerely,
SPR
