The following data structures are used:

Error-code data structure

This defines the two binary fields used and the message ID that error conditions.

Retrieve job description data structure

This defines format JOBD0100, a 390-byte data structure with the h positions 77-86.

Dummy data

structure

 

 

 

 

 

 

This

contains a field used

for

the

length

of the receiver

variabl

defined

as binary

and is

in the first 4

bytes. .The19/ dummy

data

on page

3-17) also

contains

the

format

field.

 

This data structure is used because RPG only allows binary variable defined in the context of a data structure.

The

program

retrieves the

parameter

list that is passed and initialize

be

passed

to the API.

The API is

called and places information into
