$log
$log system.date = %system.date%
$log
$log system.errorlevel = %system.errorlevel%
$log
$log The filesys is UNIX or ???? these days
$log system.filesys = %system.filesys%
$log
$log fp / fn / fe tell us what GAMS file is being compiled
$log system.fp = %system.fp%
$log system.fn = %system.fn%
$log system.fe = %system.fe%
$log
$log Memory gives the Mb (1,000,000 bytes) of allocated heap
$log Before we fully allocate a 1000x1000 matrix
$log system.memory = %system.memory%
set i / 1*1000/, j/1*1000/;
parameter A(I,J) / (#i).(#j) 1 /;
$log and after
$log system.memory = %system.memory%
$log
$log These are useful for seeing what we are running, and where
$log system.buildcode = %system.buildcode%
$log system.hostplatform = %system.hostplatform%
$log system.platform = %system.platform%
$log
$log There are several ways to get version info
$log system.gamsversion = %system.gamsversion%
$log       system.verid = %system.verid%
$log     system.version = %system.version%
