11.6 Nonrepeatable Edit Descriptors
The forms of nonrepeatable edit descriptors are:
’hh...h’ (apostrophe)
nHhh...h
Tc
TLc
TRc
nX
/
:
S
SP
SS
kP
BN
BZ
X
As an extension to the FORTRAN 77 language, the following nonrepeatable edit descriptors are also
supported.
$
\
where:
Apostrophe, H, T, TL, TR, X, /, :, S, SP, SS, P, BN, BZ, \ and $ indicate the
method of editing.
h is a character.
n and c are positive unsigned integer constants.
k is an optionally signed integer constant.
Open Watcom FORTRAN 77 allows edit descriptors to be specified using lower case letters.
11.7 Editing
Edit descriptors are used to describe the way the editing between internal representation of data and the
characters of a record in a file is to take place. When the edit descriptors I, F, E, D, G, L, A, H,
Z or apostrophe are processed, they process a sequence of characters called a field. On input, the field is
the character data read from a record; on output it is the character data written to a record. The number of
characters in a field is called the field width.
