Dear Sajith,

You need to use the statement BLOCK

For Eg.

Code: Select all  Expand view

// Menu Display Text
cMenuText:=Alltrim(oRecSet:Fields("Menu_Text"):Value)

// Convert Menu action to a code block
cMenuAction:="{ || "+LTrim(RTrim(oRecSet:Fields("Menu_Action"):Value))+" }"

MENUITEM cMenuText BLOCK &(cMenuAction)

If you are using xHarbour, you can write your code like this also:

Code: Select all  Expand view

MENUITEM oMItem1 PROMPT  oRecMenuHierarchy:Fields( "MenuHierarchy" ):Value ;  
   ACTION HB_ExecFromArray( oMItem1:oMenu:oLastItem:cPrompt )
 

This approach is simpler and does not have to concat strings and do macro evaluation
