1 and an offset of

0 are

used.

The

first example

was

explained

Instead

of

listing each keystroke,

the

following format

shows

the display after

a

value

is

keyed

in; the

the

next

entry

is

not shown.

This format

is

similar to that

used in the

PC208 EDLOG

program.

lf

you

have

followed

through

sample

program

and edited

the

program

in OV4.2,

your

21X

now has a 5

second

execution

interval and

lnstruction 17 in Table 1 .

To continue with

this

example

you

can

simply

advance

(key

through

the execution interval and

Instruction

and check

the entries against

the following

listing. The new

starts

with
