O$ - why not use #F

[Mike Matthews - Omnis]

Yes it does, as they are ‘Global’ and not used for that window or instance.  Change it once, and it changes everywhere.  They have their uses of course, so use wisely.

Thank you Phil and Rudolf.Does this phenomenon of unpredictability also apply to other global variables such as #1,#2, #L1, #L2 as used in a For loop: For #1 from 1 to #LN step 1 ?
Kind regards,Martin O.

Most developers will of moved away from relying on #F, mainly due to
things like timers, which may pop in and do something when you least
expect it, and maybe change the #F flag unexpectedly.

So using your own variable to hold any flag or status is a much safer
way to go.

  Hi Paul,
Sorry, I don't wish to be rude, but could I interject and ask why you use vbOK variable instead of using the inbuild #F variable to return the status of a flag?
Kind regards, Martin.
