All the communication done over PCOMM (Personal Communication COMM) technology. Host Access Class Library provides nice guide for the same.

Usage

AS400 instance can be created as below,

from ibm import Instance

# session "A" is marked in above image with Red box
instance = Instance("A")

out of the box two pointer are available, ps and oia pointers.

PS(Presentation Space): provides methods and properties to query and manipulate the AS400 screen objects for the related created instance.

OIA(Operator Information Area): it provides methods and properties to query and manipulate the Operator Information Area, bottom bar.

simple program can be created out of the created instance.

From the above base, more useful utility class is provided, its usage is below,

from ibm import Instance

instance = Instance(session='A')
print(instance.get_text(row=4, column=2, length=3))
# "IPL"
instance.wait(1)
# block execution for 1 second
instance.send_keys(key='[pf16]')
# above command send F16 key press and window get change

from ibm import Instance, Screen

instance = Instance("A")
screen = Screen(instance)

screen.describe("cursor", x=1, y=3)
screen.wait(5)
# wait up to 5 second for cursor to appear at (1, 3) location.
# As soon as cursor appears, it returns True else after time out returns False

text = Screen(instance)
text.describe(x=3, y=1, string="IPL", case=True)
text.wait(5)
# wait up to 5 second for IPL (case sensitive) appear at (3, 1) location.
# As soon as "IPL" appears, it returns True else after time out returns False
