Figure 3-3. Column Repetition, Page 2
Pages 3, 4, and 5 are similar, with page 3 using J = 11, ..., 15, and page 4 using J = 16,
..., 20, etc.
The index values are computed entirely within this version of the print statement. They are not
individually accessible in any other statement and should not be referenced outside this context.
The phrase a group of .. fields in a print statement notifies the compiler that a sequence
of index values generated for the enclosing column repetition block is to be used in computing the
output fields. As shown above, one format must be provided for each of the fields in the column
repetition group. If the begin report statement specifies groups of six, then six formats must be
provided in each print statement containing a a group of ... fields clause. For example,
the previous displays can be better labeled by using the statement:
for I = 1 to 6,
print 1 line with I,
and a group of X(I,J) fields as follows
* ** ** ** ** **
Several values can be alternated within a a group of ... fields clause, each using the index
values. For example, the previous program might want to display both X(I,J) and Y(I,J) as follows:
for I = 1 to 6,
print 1 line with I,
and a group of X(I,J), Y(I,J) fields as follows
* ** *.* ** *.* ** *.* ** *.* ** *.*
A format must be given for each output value, of course. All repeated formats must agree in mode.
It is not possible to write:
print 1 line with a group of I fields thus
