13.6.26 SHARE Specifier (WNT, W9*)

The SHARE specifier indicates whether file locking is implemented while the unit is open. It takes the following form:

 SHARE = shr
Is a scalar default character expression that evaluates to one of the following values:

'DENYRW'   Indicates deny-read/write mode. No other process can open the file. 
'DENYWR'  Indicates deny-write mode. No process can open the file with write access. 
'DENYRD'   Indicates deny-read mode. No process can open the file with read access. 
'DENYNONE'   Indicates deny-none mode. Any process can open the file in any mode. 

The default is 'DENYWR'. However, if you use the compiler option specifying Fortran PowerStation semantics, the default is 'DENYNONE'.
