Page 10 Computer Languages for Engineering - SS 13• DebuggerTo check an application the executable can be started within a debugger program. The commonfeatures of a debugger are supported.The disadvantage of the Open Watcom suite is, that the three regarded components are not integratedwithin one application. Figure 1.4 shows the one and only source file of the famous hello world appliaction.Double clicking the source file in the manager will start the editor application (see figure 1.4).Figure 1.4: Watcom-IDE-ManagerIf standard FORTRAN 77 is used, formating could be a problem, because Open Watcom 6 does not supportany formating highlightings. So we use a formating comment, which marks the first 7 columns of sourceline. You have to be careful too with the comment columns starting with column 73. This commentcolumns also are not marked within the coding.If the program sources are compiled, the linker creates the executable linking the object files 7 with thelibraries. To check the executable the debugger can be started from the Watcom-IDE-Manager. Figure1.6 shows a debugger session to check our famous startup example hello world.6 Here we talk about the version 1.8.7 Object files are compiled source files, created by the compiler.E. Baeck
