No, the syntax I sent enables/disables all textboxes that have class "TextBox" (those that are directly subclassed form Textbox class).
I think you want something different. Not all but only those which names match to a list? Something like:

lcEnabDisabList = 'TXTFSTNAME,TXTLSTNAME'
for ix = 1 to alines(aMemberNames,m.lcEnabDisabList,.t.,',')
 store !(this.Value=1) to ('THISFORM.PAGEFRAME1.PAGE3.'+aMemberNames[m.ix]+'.Enabled')
* or for multiple property setting
*with evaluate('THISFORM.PAGEFRAME1.PAGE3.'+aMemberNames[m.ix])
* .Enabled = !(this.Value=1)
*endwith
endfor

PS: Inlist has a parameter count limit. Using a string like this you don't have that limit.
