Syntax for CALLing an event procedure?

I knew I'd seen it somewhere, but could never find it - until now, doing a
browse of the VBDOS Programmer's Guide.

From the top of p41:

"Event procedures are SUB procedures found in form modules that are executed
when a user action or system event occurs. You can also explicitly call an
event procedure by using the CALL statement."

The capability in that last line has always escaped me. I have tried a variety
of CALL constructions without any joy, invariably attracting a "syntax error"
message.

So were the MS documenting committe on something when they wrote that, or can it
be done? If anyone can provide me with a working CALL construct to invoke say a
SUB cmdOK_Click () I'd appreciate it.

Without trying it, I would think:

cmdOK_Click

However, a declare may be needed or it might only work from the same
file, in which case you would need a wrapper sub.

I just checked some VBDOS source code (from someone else) and it is
used there, but in the same source file, with a declare.
