Exec Command


EXEC <function-name> [<sortarg>]r INIT [<initarg>]r

where <function-name> is the name of the external command,
<sortarg>r is a list of runtime arguments, eg. sortwords, spectrum names,
<initarg>r is a list of initialisation arguments to the function, eg. filenames.


The EXEC command allows externally defined subroutines to be accessed from the sort. It allows different sorting and storage algorithms to be used via the sort language. See Appendix B for the more information on the EXEC command and how to use it to access the hypercube sort function SYM4D.
