Expand: Ef

Top Previous Next

The expand parameter generates a file that contains information about all the input files processed during a particular compilation. By default names are composed by completing the name with the working directory. String input is expected.

The command is implemented with the syntax

Expand=filename

Ef=filename

Example:

parameter a ; a = 0 ;

$include file2.inc

where file2.inc contains

a = a+1;

display a;

Running the model with the command line flag expand myfile.fil results in the creation of the myfile.fil with the following content

1 INPUT 0 0 0 1 7 E:\TEMP\FILE1.GMS

2 INCLUDE 1 1 2 2 4 E:\TEMP\FILE2.INC

3 INCLUDE 1 1 3 5 7 E:\TEMP\FILE2.INC

•	The first row always refers the parent file called by the GAMS call.

•	The first column gives the sequence number of the input files encountered.

•	The second column refers to the type of file being referenced. The various types are

0 INPUT

1 INCLUDE

2 BATINCLUDE

3 LIBINCLUDE

4 SYSINCLUDE

•	The third column provides the sequence number of the parent file for the file being referenced.

•	The fifth column gives the local line number in the parent file where the $include appeared.

•	The sixth column gives the global (expanded) line number which contained the $include statement.

•	The seventh column provides the total number of lines in the file after it is processed.

•	The eighth and last column provides the name of the file.
