# _CP_trans

_CP_trans is equivalent to one of several
BASIC transaction processing statements depending on the op parameter.
Valid values of op are:

| --- | --- |
| _CP_TRANS_START | Equivalent to the BASIC begin work {str} statement. If no transaction name is desired, then pass 0 in exp and _CP_str_null in str. If a transaction name is desired, then pass 1 in exp and the desired name in str. |
| _CP_TRANS_COMMIT | Equivalent to the BASIC commit work statement. Pass 0 in exp and _CP_str_null in str. |
| _CP_TRANS_ROLLBACK | Equivalent to the BASIC rollback work statement. A 0 must be passed in exp and _CP_str_null in str. |
| _CP_CACHE | Equivalent to the BASIC transaction cache on/off statement. Pass in the on/off parameter in exp, and _CP_str_null in str. |
| _CP_FLUSH | Equivalent to the BASIC transaction flush on/off statement. Pass in the on/off parameter in exp, and _CP_str_null in str. |
