or
if none
These logical conditions obviously have no meaning outside the immediate context of a find statement.
The following statements search a number of elements of array A for one that matches the
value B, assigning a new element value if no match is found:
for I = 1 to N
with A(I) = B
find the first case
if none
let N = N+1
let A(N) = B
always
More than one for phrase can be used to control a find statement. Also more than one find variable
may be assigned in one find statement. This is done by including a list of variable assignment
phrases. The following example illustrates both features:
for I = 1 to N,
for J = 1 to M,
with FN(I) less than FN(J)
find FS(1) = the first I and FS(2) = the first J
In cases where there is no expression to compute, a special form of the find statement can be used.
The words the first case replace the variable assignment phrase. The search terminates, as
before, with the first matching value. The terminating value of the for index variable is available
for subsequent use. Both of the following statements terminate with the same value of I:
for I = 1 to MAX,
with V(I) less than QQ(I),
find the first case
for I = 1 to MAX,
with V(I) less than QQ(I),
find I = the first I
3.3 A Statement for Computing Some Standard Functions of Variables
Rather than selecting a single value satisfying some criterion, it may be desirable to summarize
some statistics of a group of values. When these values are stored in arrays, or can be computed by
some regular iteration, the compute statement facilitates compilation of descriptive statistics. An
example of the use of a compute statement is:
