Greg, Those sentences get into a codeblock, and the compiler warns when there is a logical value that does nothing. In example: local n := 1 .T. MsgInfo( "hello world" ) in the above lines the .T. has no sense at all. Now lets take that code to a codeblock: { || n := 1, .T., MsgInfo( "...

This is really a mystery to me. Here is a code block for a BUTTON that has 8 IIF statements. I was only getting two compile warnings on this block, so by elimination, I added a "placeholder" variable ph := IIF(.... to all of them and deleted one at a time and compiled to find which two lin...

However, this code compiles perfectly @ ( nHg/2 ) - 30, 2*Int( nWd/6) + 50 BUTTON oBtn1 PROMPT "Aceptar" ;             SIZE 50, 18 PIXEL OF oDlg ;             FONT oFont2 ;             ACTION ( lOk := .T., iif( lOk, oDlg:End(), .F. ) )  And this also...

Greg,

Instead of:

IIF ( lNew, oPaperDbf:append(), .t.)

try this:

IIF ( lNew, oPaperDbf:append(), )

Christobal...that does indeed work (as far as getting rid of the compiler warning..but in runtime??), but Im confused as to why it is needed. I probably have 1000's of IIF's in my programs but only a hundred or so are coming up with this compile error. The "placeholder" variable ( lwhateve...

Sorry, did not understand well your problem The solution is that the IIF function must be returned to a variable Try also: REDEFINE BUTTON oBtn4 ID 1002 OF oDlg WHEN lEdit  ACTION ;            lEdit := IIF ( lEdit, oSizeDbf:append(), .t.), ;            oSizeDbf:StkSize := STR(oSi...

Christobal,
Thanks for the quick reply. No, the functions do not return a logical, so I tried your idea of (myfunc(), t.) and it doubled the number of W0027 errors...twice as many ".t."...twice as many errors! oy vey....(and im not even jewish)
Greg

The functions myfunction() included in the IIF (<lcond>, myfunction (), T.) return a boolean?
If not, try like this: IIF (<lcond>, (myfunction (), T.), T. )
