ALLDONE: ENDPGM

As an alternative to using the job log, the following RPG program uses code structure to receive error messages:

H\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

H\

 

 

 

 

 

 

\

H\ MODULE: ERRCODE

 

 

 

 

\

H\

 

 

 

 

 

 

\

H\ LANGUAGE: RPG

 

 

 

 

\

H\

 

 

 

 

 

 

\

H\ FUNCTION: THIS APPLICATION DEMONSTRATES THE USE OF THE

\

H\

 

ERROR CODE PARAMETER.

 

 

 

\

H\

 

 

 

 

 

 

\

H\ APIs USED: QHFRTVAT, QHFCRTDR

 

 

 

\

H\

 

 

 

 

 

 

\

H\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

H\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

H\

 

 

 

 

 

 

\

H\ THIS PROGRAM DOES SOME SIMPLE VERIFICATION ON AN HFS

\

H\ DIRECTORY. THE QHFRTVAT API IS USED TO VERIFY THE EXISTENCE

\

H\ OF THE SPECIFIED DIRECTORY. IF THE DIRECTORY DOES NOT EXIST, \

H\ AN ATTEMPT IS MADE TO CREATE THE DIRECTORY.

\

H\

 

 

 

 

 

 

\

H\ THERE ARE THREE PARAMETERS TO THIS PROGRAM

\

H\

 

 

 

 

 

 

\

H\

1

INPUT

PATHNM - NAME OF DIRECTORY

\

H\

2

INPUT

PATHLN - LENGTH OF PATHNM PARAMETER

\

H\

3

OUTPUT
