You need to include the maths library at the link phase of either creating a bespoke runner (e.g. using 'cfglgo') or compilling your 4GL program - '-lm' should do the trick. For RDS runner make a private copy of 'cfglgo' and append '-lm' to the libaries listed in 'LIBES='. For a 4GL program (e.g. producing a '.4ge') you need to amend the makefile (or whatever) you are using to control the build to include '-lm' where is is using 'cc' to link the '.o' files into the '.4ge'. -- ============================================================================ Sally Woolrich | This mail contains my personal sally@excelsis.demon.co.uk | views not those of my employer! ============================================================================
