Query Arrays

If the attribute is an array, the query will return a list of values. Individual elements can be queried by passing in the index number.

!VALUE = !!CE.DESP[2]

!VALUE = DESP[2]

Alternatively, the NUM keyword can be used for PML 1 syntax. A range of values can be returned using the TO keyword.

VAR !VALUE DESP NUM 3 - to retrieve the 3rd value

VAR !VALUE DESP NUM 3 TO 5 - to retrieve 3rd to 5th values

Q DESP NUM 3 TO 5

An error will occur if attempting to query off the end of the array.

Within a PML1 expression, a position attribute may be queried as an array in order to access the individual coordinates.

VAR !X (POS[1] ) - This will return the X coordinate.
