Dynamic Names for GDX Files

Under certain circumstances one may want to use a dynamically generated filename for gdx files. The put_utility can be used to achieve this:

scalar i;
for (i=1 to 10,
 put_utility 'gdxout' / 'out' i:0:0;
 execute_unload i;
);
for (i=1 to 10,
 put_utility 'gdxin' / 'out' i:0:0;
 execute_load i;
 display i;
); 

The log file reads:
