When M0 changes from 0Æ1, if D0 =2, the contents
of file registers F200~F249 will be overwritten by the
content of data registers R0~R49. the record length is
50.
.Pointer will be increased by 1 after operation.
.When M0 changes from 0Æ1, if D0 = 1, the content
of data registers R0~R49 will be overwritten by the file
registers F150~F199.
.The record pointer will be increased by 1 after
