Using the CBRXLCS macro in an assembler environment

Perform the following steps to use the CBRXLCS macro in an Assembler language environment:

Include mapping macro CBRLCSPL to provide a DSECT for the LCS External Services parameter list, as follows:
```
         CBRLCSPL
```
Create copies of the LCSPL in both static and dynamic storage using the LIST form of CBRXLCS, as follows:
```
         CBRXLCS  MF=(L,static-list-name)
         CBRXLCS  MF=(L,dynamic-list-name)
```
Note: No other keywords can be supplied on the LIST form of CBRXLCS.
Initialize the LCSPL by copying the static LIST form to the dynamic LIST form.
Rule: Because the length of the LCSPL exceeds 256 bytes, you must use the MVCL instruction for the copy.
Set parameter values in the LCSPL using the MODIFY form of CBRXLCS, as follows:
```
         CBRXLCS  keywords,
              MF =(M,dynamic-list-name)
```
Rule: If you use the MODIFY form of the macro, you must follow it with the EXECUTE form.
Set the parameter values in the LCSPL using the EXECUTE form of CBRXLCS and invoke LCS External Services to perform the requested function, as follows:
```
         CBRXLCS  keywords,
               MF=(E,dynamic-list-name)
```
Note: You can use the EXECUTE form of the macro without having previously used the MODIFY form.
To check the completeness and compatibility of the set of parameters supplied on a single invocation of CBRXLCS, specify one of the following statements using the MODIFY form of the macro or the EXECUTE form of the macro, as follows:
```
         CBRXLCS  keywords,
               MF=(M,dynamic-list-name,COMPLETE)
                  or
         CBRXLCS  keywords,
               MF=(E,dynamic-list-name,COMPLETE)
```

There is no standard form of the CBRXLCS macro for Assembler language.
