USING THE UTILITY PROGRAMS
All programs (except the Automatic System Build, Storage to Diskette Dump, and
Storage to Printer Dump) are IPLed from the disk. All programs are on disk in a
storage-image format, preceded by a header record designating the load point, entry
point, size of the program, and maintenance information.
To invoke a program, set the IPL switch to primary (disk) and press the LOAD key on
the system console. Once the loader is in main storage, it prints a message at the operator
station requesting the name or starting sector address of the program to be loaded:
IPI00A EXEC=
You can enter either the 2-character name for the IBM-supplied programs (for example,
RI
for diskette initialization) or the program's starting sector address. For any other
programs, you must enter the program's starting sector address. Sector addresses must be
specified in this format:
ccchss
where:
ccc the cylinder number
h the head number
ss the sector number
After the program is loaded, it issues prompts at the operator station requesting you to
enter certain information needed by the program before it can begin processing. This
information is covered in the chapters describing the individual utilities.
The utility prints an error message at the operator station and reissues the prompt if (1)
the information you enter is syntactically incorrect or (2) if the utility encounters a
recoverable error. Each time a prompt or message is printed at the operator station, it
ends with a carriage return. You must also end your entries with a carriage return.
If you are typing a line that is longer than 72 characters, there is an automatic carriage
return after you type the 72nd character.
In the Series/l programs, a contiguous, logically related collection of data on a
single disk or diskette is called a data fIle. Through the operator station, you can refer to
a data fIle by specifying its device address, starting sector address, and ending sector
address. Enter the information in this format:
ddd ,ccchss,ccchss
where:
ddd = the device address
ccchss,ccchss = the starting and ending sector addresses of the data fIle
The device address are fixed as follows:
Device Address Device Type
000
001
002
003
operator station
printer
diskette
disk
The ranges of the ccc, h, and ss values are:
cylinder (ccc)
Diskette-double-sided 0-74
Disk
Disk
-single-sided 0-74
0-302
head (h)
0-1
o
0-1
sector (ss)
1-26
1-26
0-59
Note. Cylinder 0 of the disk is reserved for the Bootstrap and Loader; cylinder 1 is
reserved for alternate sector assignments; cylinder 302 is reserved for customer engineer
use. On the diskette, track 0 is reserved for system use; tracks 75 and 76 are reserved as
al ternate tracks to replace tracks that become defective.
