Candidate REXX Extensions

This document describes the candidates for extensions to the existing REXX Standard:

• USE ARG - usage of parameters by reference instead of by value

• IFF(cond,a,b) - return a if cond is true, b otherwise

• // single line comments

• handling of lists

• generic data structures like APL2

• remote procedure calls

• integrated library management (REQUIRE from a local and/or remote repository)

• trigonometric, root and exponential functions

• word(string,index,delimiter) - adding the delimiter - e.g. to parse CSV files; default would be " "

• an OPTION statement, e.g. to specify decimal or binary arithmetic

• a LOOP statement following ooRexx and NetRexx practice
