Subject:	SCOUG-Programming: REXX file lock/unlock, program instances

Content Type: text/plain

In REXX,

-- How do I lock a file, unlock it after using it, and what error code
does another program receive if it attempts to open/lock an
already-locked file?

-- How can an executing REXX .cmd file find out if it is already
running?

Thanks.

- Peter
