This program illustrates the use of the automatic macro variable `_SASPROGRAMFILE` (often available in environments like SAS^© Studio or in batch mode). It uses macro string manipulation functions (`%qsubstr`, `%length`, `%scan`) to isolate the file name without its extension or to obtain only the parent directory path.

Data Analysis

Type : INTERNAL_CREATION

The script does not manipulate any data tables; it only interacts with system macro variables.

1 Code Block

3 Code Block

MACRO

Explanation :
Isolates the parent directory by subtracting the length of the file name (found via `%scan` with the '/' delimiter) from the total length of the string.

Copied!

1	%put %qsubstr(&_SASPROGRAMFILE,1,%LENGTH(&_SASPROGRAMFILE)-%LENGTH(%scan(&_SASPROGRAMFILE.,-1,'/'))-1);
