Displaying Fields as Hexadecimal Values

You can use the EVAL debug command to display the value of fields hexadecimal format. To display a variable in hexadecimal format, type

EVAL field-name: x number-of-bytes

on

the

debug

command line. Thefieldvariable-nameis

the

name of

the field

tha

you

want

to display in hexadecimal' ' specifiesformat. that the field is to

played

in

hexadecimal format. Thenumbervaria-of-bytesle indicates the number

of

bytes

displayed.

If no

length

is'x',specifiedthe sizeafterof thethe field

is

used as

the

length. A minimum of 16

bytes

is

always

displayed.

If

field

is

less

than

16

bytes,

then

For example, the field String is defined as six-character string. To

hexadecimal equivalent of the first		3 characters, you would enter:
EVAL String: x 3
Result:
00000	C1C2C3	- ABC

For example, in the program DEBUGEX, data structure DS2 does not have subfields defined. Several MOVE operations move values into the subfie

Because there are no subfields defined, you cannot display the da

Therefore, to view	its	contents you can use the character display
EVAL DS2:C 20	Result:	DS2:C 20 = 'aaaaaaaaaabbbbbbbbbb'
