Environment functions

This chapter describes the built-in 4GL functions used to manipulate the environment:

• fgl_arch() shows the architecture on which the compiled binary is running
• fgl_getenv() returns the value of the specified environment variable
• fgl_getpid() retrieves the system process identifier (pid) for the current program
• fgl_getresource() returns the value of an FGLPROFILE resource
• fgl_getversion() returns the version number of the 4GL runtime library currently in use
• fgl_putenv() and fgl_setenv() set values for environment variables
• fgl_username() returns the user name under which the current process is run
