To do this, use the ‘Address’ look-at type, and type in the address ofthe status bit/s to operate on (e.g. T0001). This will also find the first operand of a timer/counterinstruction (e.g. If T0001 is looked for, then ‘1’ will also be found in the TIM instructions).Therefore, it is possible to change a range of TIM numbers to another offset.Revision 2.0Page 49CHAPTER 3 – Project ReferenceOMRONFinding and Replacing SymbolsIt is possible to perform a replace on 'Symbol Names' within a program, but this only updates theprogram, so that the new name is inserted as the operand. The replacement within the program does notaffect the underlying symbol definition.When a symbol name is updated in the symbol table, the programs using the symbol will also be updatedto use the new name.Note:It is not possible to change the definition of a symbol from within a program. i.e.
Asymbol's comment or name cannot be changed unless the replace is happening withinthe symbol table.PropertiesEach window or object in CX-Programmer has associated Properties that can be displayed.
