Prototype: getindices(varref)

Return type: slist

Description: Returns the list of keys in varref which can be the name of an array or container.

This function can accept many types of data parameters.

Make sure you specify the correct scope when supplying the name of the variable.


  • The function always returns a list. If called on something that has no index (for example, an undefined variable) an empty list is returned.

  • The list which getindices returns is not guaranteed to be in any specific order.

  • In the case of a doubly-indexed array (such as parsestringarrayidx() and friends produce), the primary keys are returned; i.e. if varref[i][j] exist for various i, j and you ask for the keys of varref, you get the i values. For each such i you can then ask for getindices("varref[i]") to get a list of the j values (and so on, for higher levels of indexing).


  • varref: string, in the range: .*
