limits	record.	If	the	two limits	supplied by the record-address
the	records	with	the	specified	key	are	retrieved.

The program repeats this procedure until the end of the record-add reached.

Examples of Sequential-within-Limits Processing

Figure 152 on page 302 shows an example of an indexed file being pr sequentially within limits. Figure 154 on page 303 shows the same examp externally described files instead of program-described files.

Figure 144 on page 294 shows the data description specifications (DD physical file used by the program ESWLIM1 ( Figure 152 on page 302) ESWLIM2 ( Figure 154 on page 303).

EXAMPLE PROGRAM 1 (Sequential-within-Limits Processing):	EMPMST	is
processed sequentially within limits	(L in position 28)	by the record

LIMITS. Each set of limits from the record-address file consists of

employee	numbers	of	the	records	in the EMPMST file to be	processed.
the employee number			key	field (ENUM) is five digits long,		each	set
sists of two 5-digits keys. (Note that ENUM is in packed						format,	the
requires	three	positions		instead	of five.)
