Re: How to convert ascii value to hex in RPGLE -- RPG400-L

The error messages are pretty descriptive of the problem. There is no definition for field LEN.

Perhaps you are making the mistake of thinking that defining LEN in a prototype defines it? It doesn't - prototypes do not define fields - they specify the requirements for a parameter.

All errors devolve from that single error. Including the message about a missing prototype.

Hi,

I tried to write RPGLE program so that i could directly first convert key
field value from file K1 to ASCII and then ASCII to HEX using QDCXLATE and
CVTHC APIs respectively but now the program itself is not getting compiled.
eventhough fasterways are available using online links but to achieve the
same functionality in AS400 program i was trying it.

please find the below link where i tried to read the file k1's field KEY
and then tried to assign it's hex value to my openssl command but it seems
program itself is not getting compiled.

To get the same value you will need to convert your data to ascii before
converting to hex.

Store directly the hex in a char field and avoid all problems. The
previously converted field will use twice the space, but save you a lot
of trouble.

Ok,thanks but program shown in this link is converting hex value
incorrectly if i compare it from
website link from below:
*https://www.rapidtables.com/convert/number/ascii-to-hex.html
<https://www.rapidtables.com/convert/number/ascii-to-hex.html>*

Hex value from program:-HEXEQUIVALENT =
'D196954081958440E2A4A28195406040D78199A3958599F4F0F0'

TESTSTRING = 'Jon and Susan - Partner400'

but HEX value as per below link is different for same text string (' 'Jon
and Susan - Partner400' ).

*https://www.rapidtables.com/convert/number/ascii-to-hex.html
<https://www.rapidtables.com/convert/number/ascii-to-hex.html>*

hex value :-4a 6f 6e 20 61 6e 64 20 53 75 73 61 6e 20 2d 20 50 61 72 74

6e

65 72 34 30 30

I tried below link but it's not working showing same error :-

Ideally HEX Value of the key(661e275OIM1ULYLJ) used here
is 363631653237354f494d31554c594c4a but program advised to use HEXAPI is
giving wrong HEX value it's
giving value in debug mode like this :-HEXEQUIVALENT =
'F6F6F185F2F7F5D6C9D4F1E4D3E8D3D1 '

So that might be the reason my program is failing and giving above
mentioned error.

Thanks

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);

Hi,

Just realized i had put + sign incorrectly at this statement in my

program

which i shared in previous email link.

1. callp ToHex(HexEquivalent:+
2. KEY: %len(KEY)*2);

after removing it though it got compiled successfully but when trying

to

run giving error
