You could also use a single, two-dimensional, array, or array references, since perl supports complex data structures.

Hi,
I'm just trying to use a dynamic index for some array elements that I'm accessing within a loop. Specifically, I want to access an array at variable position $counter and then also at location $counter + 1 and $counter + 2 (the second and third array positions after it) but I keep getting...

xkbkeysymentry
XkbKeySymEntry(3) XKB FUNCTIONS XkbKeySymEntry(3)
NAME
XkbKeySymEntry - Returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key
corresponding to keycode
SYNOPSIS
KeySym XkbKeySymEntry macro ( xkb, keycode, shift, grp )
XkbDescPtr xkb;
KeyCode keycode;
int shift;
int grp;
ARGUMENTS
- xkb Xkb description of interest
- keycode
keycode of interest
- shift
shift level of interest
- grp group of interest
DESCRIPTION
The key width and number of groups associated with a key are used to form a small two-dimensional array of KeySyms for a key. This array
may be different sizes for different keys. The array for a single key is stored as a linear list, in row-major order. The arrays for all of
the keys are stored in the syms field of the client map. There is one row for each group associated with a key and one column for each
level. The index corresponding to a given group and shift level is computed as:
idx = group_index * key_width + shift_level
The offset field of the key_sym_map entry for a key is used to access the beginning of the array.
XkbKeySymEntry returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key
corresponding to keycode.
