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