To reduce compilation time, KAP estimates the length of time required to analyze each loop nest construct. If a loop is too deeply nested, KAP ignores the outer loop and recursively visits the inner loops. The loop nest limit is a rough dial to control what KAP considers too deeply nested.
Loops that exceeded this threshold will be marked in the Loop
Table (/listoptions=l ) in the listing file. (See Chapter 10.)
Larger loop nest limits may allow more optimizations to be performed
for deeply nested loop structures, but may take more compilation
time. The limit does not correspond to the DO loop nest level;
rather, it is an estimate of the number of loop orderings that can
be generated from a loop nest. The /limit qualifier
resets this internal limit. The loop nest limit can also be modified
with the C*$* limit <integer> directive. Most users do
not need to change this value.
