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

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 compiler option /fpscomp=general or the SHARED specifier is used, the default is 'DENYNONE'.
