Displaying the Contents of an Array

Specifying an array name with EVAL will display the full array. To disp element of an array, specify the index of the element you wish to theses.

To display a range of elements use the following range notation:

EVAL field-name (n...m)

The	variablefield-name is			the	name	of the array,n isthea variablenumber repres-
enting the start of				the	range,	andm	isthea	variablenumberrepresenting the end
of	the	range.
Figure 98		shows	the use of EVAL			with	the	array in DBGEX.
> EVAL Arry					3S 2 DIM(2) INZ(1.23)
	ARRY(1) = 1.23		** Display full array **
	ARRY(2) = 1.23
> EVAL Arry(2)			** Display second element **
	ARRY(2) = 1.23

>EVAL Arry(1..2) ** Display range of elements ** ARRY(1) = 1.23

ARRY(2) = 1.23

Figure 98. Sample EVAL commands for an Array

Displaying the Contents of a Table

Using EVAL on a table will result in a display of the current table e display the whole table using the range notation. For example, to displ

3-element table, type:

EVAL TableA(1..3)

You	can	change	the	current		element		using the %INDEX built-in function. To
mine	the	value	of the table			index,		enter		the	following command:
EVAL _QRNU_TABI_name
wherename		represents		the	table		name	in	question.
Figure 99		on page 203		shows	the		use	of	EVAL	with	the table in DBGEX.
