Using AsHexString

[MARCOREMMEDATA]

Hi

I've to convert a integer value in Hexadecimal. But intrincic function AsHexString give back a wrong value.
can you help me understand if I am using the function incorrectly?

The value is 49202, Window Calc for HEX is C032 for lansa il 32C00000

Howdy! Agreed, it looks like the intrinsic method doesn't work. I created a quick form / routine to do the conversion; it isn't very elegant, but the uDec2Hex routine seems to return the correct value, so maybe you can use it as a starting point?

Hi

thank you.

I realised that the intrinsic function works but in reverse. The Hex string is inverted for pairs of characters

In a old Lansa newsletter https://lansa.com/downloads/support/new ... feb10e.pdf pag 19

Int: 49202, Window Calc for HEX: C0 32; lansa: 32 C0
Int:169999999999, Windows Calc for HEX: 27 94 CA 23 FF; lansa: FF 23 CA 94 27

I solved it by reversing the string

Code: Select all

DEFINE FIELD(#CC) TYPE(*DEC) LENGTH(3) DECIMALS(0)
DEFINE FIELD(#CRC) REFFLD(#RTE_PNPDU)
DEFINE FIELD(#REVERTCRC) REFFLD(#RTE_PNPDU)
DEF_ARRAY NAME(#REV) INDEXES(#CC) OVERLAYING(#REVERTCRC) TYPE(*CHAR) ENTRY_LEN(2)

#REVERTCRC := ( 49202 ).AsBinString.AsHexString

#CRC := ""
BEGIN_LOOP USING(#CC) FROM(128) TO(1) STEP(-1)
CONTINUE IF((#REV#CC = '00') *Or (#REV#CC = ''))
#CRC += #REV#CC
END_LOOP

Howdy!

I noticed the octets seemed to be reversed as well. Personally, I would not use the code to reverse the errant values because you never know when LANSA might provide a correction to the intrinsic method in an EPC/upgrade, which would then cause the application to start returning incorrect results. That's just my opinion though.

Take care!

Fix maybe a hot fix, clearly a defect, if you are in maintenance, try to get that. That will solve the issue for you and everyone trying to use the same intrinsic
