Before a jBC program can be run it must be cataloged after it is compiled with the BASIC command. This is the preferred way to run a jBC program (excluding subroutines, functions and methods).
The CATALOG command creates an executable file that can be launched in the same way as any other executable:
- from the command line
- from a Unix script file (e.g. .profile)
- from a Windows .cmd or .bat file
- from a Windows shortcut
- from a PROC
- from a PARAGRAPH
- using the jBC EXECUTE/ PERFORM statements
- using the jBC ENTER or CHAIN statements
# The RUN command
jBASE also provides the RUN command to launch an executable.
This exists solely for compatibility with older systems. Because there is a resource overhead in using RUN, we recommend RUN is not used.
Note that using RUN does not remove the requirement to CATALOG jBC programs.
RUN can be used as :
RUN SourceFileName ProgramName (options
The SourceFileName is used as a place holder only, so specifying a different source file does not change the version of the program that is run.
If your program file is a directory, does not have an OBJECT data level and the program name does not end in ".b", then the RUN operation will attempt to catalog "on-the-fly" if the catalogued routine is not already available.
