Mel,

Yupp! that was my fault. Sorry

DEFINE CLASS tmrAction as timer
nDelay   = 20
cCommand = ""
Enabled  = .F.
Interval = 0

PROCEDURE TIMER   &&  <--- !!!!
  local lcCMD

  *-- Make sure the timer only fires once!
  this.enabled = .F.

  lcCMD = allt(this.cCommand)
  &lcCMD
ENDPROC

PROCEDURE SETTIMER(tcCommand as String, tnInterval as integer)
  local lnDelay
  lnDelay       = iif(vartype(tnDelay)="N", tnDelay, this.nDelay)

  this.cCommand = tcCommand

  this.Interval = lnDelay
  this.Enabled  = .T.
ENDPROC

That should work better <g>
