# C.1 CRC-String

Selecting this option, a checksum is written both to the resource itself (as a free string) and the header file. This can be used by a program to determine whether the correct resource file has been loaded.

Whether a CRC string is stored, can be specified in File/Output files with the option CRC-String.

The export uses following variables:

_RSM_CRC_: | Index of the free string containing the CRC-string
_RSM_CRC_STRING_: | CRC-String value (should match the string from the resource)

Note: The CRC-string can be used to check wether a resource file has been changed in an incompatible way. For the calculation of the checksum, object types, object numbers and their links are used, but not texts and positioning.
