Setting this configuration variable to "1" (on, true, yes) causes ACUCOBOL-GT to treat all indexed files as if they had the WITH COMPRESSION phrase specified for them. This affects the status of newly created files only. When the configuration variable is set to the default value of 0 (off, false, no), only those files with the WITH COMPRESSION phrase specified will be compressed. You can specify the amount of compression with the COMPRESS_FACTOR configuration variable.
