EGL creates sample control language (CL) for running a called program on iSeries®. The file name is alias.clr, where alias is set by the alias property for the program, truncated to 8 characters; or if the alias property is not specified, the program name, truncated to 8 characters. During the preparation phase of generation, the sample runtime CL is copied to the QVGNCLS file in the destination library with the name alias_R. It is then compiled. You can tailor the sample runtime CL after it is transferred to the iSeries host. Alternatively, before you generate output code, you can customize the template that EGL uses to provide the basic pattern for the sample runtime CL.
