Predefined local variables

Every script contains some predefined variables. All predefined variables are declared as constants, so they may not be changed from the script.

Value Group of local variables Value type Meaning
QUERY action
0 _Q_YES INT Positive response to an action.
1 _Q_NO INT Negative response to an action.
2 _Q_TIMEOUT INT Exceeded the maximal wait time on action.
3 _Q_DONTKNOW INT Response to an action.
Variables describing an error
- _ERR_LINE INT Line, where the error occurred.
- _ERR_NR INT Error number.
- _ERR_NR_TRANS_EX INT Extended error number - list of existing errors.
- _ERR_MSG TEXT Error message.
Database opening parameters
1 _DB_READ INT ''Read only'' access to the database.
2 _DB_MODIFY INT ''Modify'' access to the database.
Parameters from process D2000 HI
- _FROM_HIP ALIAS If the script is started from process D2000 HI, then the variable contains the reference to the given process.
- _HIP_PAR_STR TEXT If the script is started from process D2000 HI, then the variable contains the parameter declared during event linking.
- _HIP_USER_DESC TEXT If the script is started from process D2000 HI, then the variable contains the name of logged-on user. After logging off the user and then logging on the other one to D2000 HI, this variable is updated.
