Arguments
grfa
The global RFA whose CRC is being returned.
Discussion
%GETCRC is a ^VAL function that returns the internal CRC of a GRFA as an i4 value. The value is a portable integer that can be compared across platforms.
This function is available to help avoid problems if the GRFA format were to change in a future version.
