What is the Cyclic Redundancy Check (CRC)?
GOAL:
What is the CRC?
GOAL:
CRC definition
FIX:
An algorithm used to verify the integrity of a file by comparing a stored number with the value calculated from the contents of some other related files. If the calculated value equals the stored number, then the first file and its relatives are considered consistent. In Progress, r-code files store the CRC value calculated from the schema against which they are compiled. If the schema changes, so does the CRC. Thus, the r-code files that contain the old CRC are considered inconsistent and cannot be run with the new schema.
