Single Value of an Array
If assigning via a PML variable, an index number may be specified in square brackets.
!!CE.DESP[2] = 99
If assigning via the attribute name, a single value of an array may be set using the NUMB keyword. The NUMB keyword follows the attribute name, and is followed by the index number.
DESP NUMB 2 99
This sets the 2
nd
value of the array to 99.
The NUMB command actually specifies the start point for a list of values.
DESP NUM 3 99 100 101
This would set the 3
rd
value to 99, the 4
th
to 100 and the 5
th
to 101.
The new values may go off the end of the existing array, but the start point must not be more than one beyond the existing end point.
DESP 1 2 3 - set up initial values
DESP NUMB 4 99 - OK, as at end
DESP NUMB 6 100 - Error, as would leave a gap
