Functions can be added to ARexx by means of external libraries . One
such library is included with the distribution of ARexx. Called
'rexxsupport.library', it should be present in the user's libs: directory
after ARexx is installed.
The library adds several Amiga-specific functions that are not defined as
a standard part of the REXX language. Included are memory-control
functions like ALLOCMEM() , file system functions like MAKEDIR() , and
interprocess-communication functions like OPENPORT() .
The functions in rexxsupport.library will not automatically be available
to ARexx scripts, however. The are available only if the library is
explicitly added to the list of libraries through which ARexx searches to
find functions.
That can be done with the ADDLIB() function or with the RXLIB command
utility. Examples of loading the library are included with the description
of each of those methods.
Frequent users of ARexx may wish to add rexxsupport.library to the system
during the startup sequence.
