Re: How to convert ascii value to hex in RPGLE

[Frank Kolmann <frank.kolmann@xxxxxxxxx>]

Hi

You could roll your own convert to hex routine.
A long time ago I coded a hex converter in RPG III.
This  following is a port to RPG ILE
I havent run this code snippet I copied it from another program I posted 
in the wiki.
But the general idea is to calculate the index to the hex character in 
the CRS array by turning low order bits off then high order bits off.
It converts the 1 byte FLD to hex in the string RU.


     D                 DS
     D  BIN                    1      2B 0
     D  HX1                    2      2
     D  HX2                    1      2

     D RU              S            255    varying
     D FLD             S              1
     D X0F             C                   X'0F'
     D XF0             C                   X'F0'
     D Z               S              5  0
     D CRS             S              1    DIM(16) CTDATA PERRCD(16)

             BIN = 0;
             HX1 = FLD;
             HX1 = %BITAND(HX1  : XF0);
             Z   = BIN / 16 + 1;
             RU  = RU + CRS(Z);

             BIN = 0;
             HX1 = FLD;
             HX1 = %BITAND(HX1  : X0F);
             Z   = BIN  + 1;
             RU  = RU + CRS(Z);
