libname np xlsx "/home/rachelgabbard0/EPG194/data/np_info.xlsx";
/* Enterprise Guide: */
libname np xlsx "&path/np_info.xlsx";
this is my code and this is the warning I get
WARNING: Apparent symbolic reference PATH not resolved.
I am in the essentials course and am trying to learn SAS for work.
Hello,
&path -- This is referencing a macro variable, you need to learn about macros in SAS.
Macro variable 'path' has to be defined first in order to reference it later.
For example:
%let path = /home/rachelgabbard0/EPG194/data;
options symbolgen;
libname np xlsx "&path/np_info.xlsx";
Here the Symbolgen option will tell you the values that was replaced in place of the macro reference in log.
In log:
SYMBOLGEN: Macro variable PATH resolves to /home/rachelgabbard0/EPG194/data
This means &path was replaced by /home/rachelgabbard0/EPG194/data
&path in this case is a macro variable
However, the error message indicates that macro variable &path does not exist, and so it can't be used.
Thus you have to give &path a value (it's probably a folder name where the Excel file np_info.xlsx is stored). So on my computer, I could use this line of code at the start of my program:
%let path=c:\users\pmiller\documents;
Naturally, your value for path will be different.
