This configuration variable specifies whether ACUCOBOL-GT does a READ for records before performing a REWRITE. It is only used for the ACUCOBOL-GT interface to CISAM.
If this variable is TRUE (ON, YES, 1), then ACUCOBOL-GT first does a READ before a REWRITE. This has the effect of making sure the record is locked before trying to rewrite it. The default is FALSE (OFF, NO, 0)
