Edit descriptors

Chapter 9 257

Table 9-18 provides examples of the logical edit descriptor on input.

Output

The character T or F is right-justiﬁed in the output ﬁeld, depending on whether the value of

the list item is true or false. Table 9-19 provides examples of the logical edit descriptor on

output.

M and N edit descriptors

Edit descriptors M and N are used to output numeric values in formats normally used for

currency.

For example, the N edit descriptor will output a value 1234.5 in the format 1,234.50; the M

edit descriptor will cause this same value to be output at $1,234.50.
