The B Edit Descriptor

The binary edit descriptor is used to display or interpret data values in binary (base 2)

integer form.

The B edit descriptor has the following forms:

w OR Bw.m

w an unsigned integer constant that defines the total field width and cannot

exceed 255. The field processed is the

w characters starting at the current

position. After the field is processed, the current position is advanced by

characters.

m an unsigned integer constant that defines the number of digits that must be

present on output.

The B edit descriptor is used in the same manner as the I edit descriptor where the

number base (

b) is 2, except that the B edit descriptor always treats the internal data

value as unsigned. (Refer to the description of the I edit descriptor, later in this

appendix.) For example, if the data item is an INT(16) in TAL, the following

conversions take place:

The “|” character is used to denote the boundaries of the output field.

The D Edit Descriptor

The exponential edit descriptor is used to display or interpret data in floating-point

form, usually used when data values have extremely large or extremely small

magnitude. The D edit descriptor is of the form:

w.d

This descriptor is identical to the E

w.d descriptor.

This edit descriptor is used in the same manner as the E edit descriptor (below).
