Description
The CRC32() function is used to return the CRC32 checksum value for the character string, <expC>. Use CRC32(RTOS()) to calculate a CRC32 checksum of the current record.
From v7.2, the CRC32_RECORD() function can be used to calculate a CRC32 checksum of the current record.
Example
? crc32("Lianja")
