This command is used to map the specified file into a bank. The bank created will be the same size as the file. Any modifications made to the bank will automatically be reflected within the file.
For the first form of this instruction, the file must exist, and must not be empty, as it is not possible to map to a zero-sized file.
For the second form, if the file does not already exist, it will be created. If the file is smaller than the minimum size specified, it will be extended to become that size.
It is allowable for the file to be included with the EXE during compilation, although all changes will be lost once when the program is stopped. |
