IBM Houston Automated Spooling Program

The Houston Automated Spooling Program, commonly known as HASP, was developed by IBM Federal Systems Division contractors at the Johnson Space Center in Houston. HASP was a program that ran on a separate computer from the mainframe, communicated with the mainframe through a bisync communications protocol, and performed supplementary job management, data management, and task management functions such as: scheduling, control of job flow, and spooling.

The program was sometimes referred to as Houston Automated Spooling Priority.

The program became classified as part of the IBM Type-III Library.

In MVS, HASP incorporated RJE and became JES2, one of two versions of the Job Entry Subsystem. It was many years before the HASP labels were removed from the JES2 source, and the messages issued by JES2 remained prefixed with "$HASP".

HASP emulators for various kinds of computers were later developed by third parties.

HASP JOB LOG output provided a summary of the resources used for the job (output appeared in all caps):

TIME START and TIME STOPPED
* CARDS READ
* CARDS PUNCHED
* START I/O
* LINES PRINTED
