categorized question QandAEditors Quickly, I'm hoping to be able to do the following; depending upon data stored in a file, I'm looking to call a subroutine if the value of a variable of the same name = 1. Is this possible? Is there an easier/more efficient way? A slightly longer version: data file contains the following: main_menu:1:1 'main_menu' is the name of the subroutine 1:1 refers to screen position(0=left 1=right) and hide/display. This data is read by sub build_menus. Simply using 'if' statements, a series of menu 'blocks' are built up to be displayed on screen. I had been using static files with straight HTML, but nor wequire that the links which are built dynamically contain other veriables appended to the URL (eg: $language, $menu_option, etc...) and am thinking of using a sub routine to build the URLs - rather than using a substitution script to parse the URL after it's been built. Hope this helps so that someone can help me. Kind regards from Andorra Richard. 1833
