>You can either modify the doform method to accept an additional parameter and modify your doform() call to send values for the other parameters as well or create a 2nd method such as doformp() and copy and paste the code from doform into and modify it and call it instead. I gave an example below of modifying the doform method to accept a parameter to pass to the form. However, in your case, since you want to pass a parameter, if the form already is open you don't want to show it like the code does below but rather close it and reopen it passing the parameter so you should create a new method like doformp() to call instead and modify it meet your needs.

Here is the modified piece to be precise:

IF !EMPTY(tcCharParam)
      DO FORM (lcFileName) NAME THIS.aForms[THIS.nFormCount] LINKED NOSHOW WITH &tcCharParam
   ELSE
      DO FORM (lcFileName) NAME THIS.aForms[THIS.nFormCount] LINKED NOSHOW
   ENDIF

and the call would be oApp.doform('myform',.f.,.f.,.f.,.f.,.f.,['my new value',0,.t.,{2000-05-05}]), e.g. all parameters would be passed as string. I have a method ValToStr to convert any passed value to its character representation.

Sorry, just realised you used only one character parameter. Using macro we can pass multiple parameters.
