I understand that the Perl validation suite fails because it presumes IEEE. And Perl suffers from a Unicode-EBCDIC conflict. It would be interesting to see a port of Perl in Ehanced ASCII and IEEE flavor. How does printf() handle it? I know it's ASCII-savvy; I haven't tried IEEE. Is there a single subroutine with multiple paths for ASCII/EBCDIC and HFP/IEEE (DFP?) and AMODE 31/64 and ...? Or are there (Cartesian product) different subroutines selected by the compiler according to feature test macros? Is the pseudo-assembler listing generated by the compiler using the output from the optimizing backend, somehow fed back to the compiler? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
