11.3.1 Forms for Control Edit Descriptors

A control edit descriptor takes one of the following forms:

c
cn
nc

c
Is one of the following format codes: T, TL, TR, X, S, SP, SS, BN, BZ, P, :, /, \, $, and Q.

n
Is a number of character positions. It must be a positive integer literal constant; or variable format expression; no kind parameter can be specified. It cannot be a named constant.

The range of n is 1 through 2147483647 (2**31-1) on Alpha and ia64 processors; 1 through 32767 (2**15-1) on ia32 processors. Actual useful ranges may be constrained by record sizes (RECL) and the file system.
