We’re asuming the GEN is a field on the screen format.
That the program does an EXFMT of the screen format before it reaches this point.
Run your program, enter a value in the field press enter
When you get the error select D for dump
Check the spool files for the dump listing.
You will want to search for the values of the fields
GEN and Res_tmp,

How to give spaces here while typing .. HTML usually collapses extra spaces out of normal text. Formatting is required to preserve spaces, or 'required space' characters might be used when typing. I'd say that the part of the page that displays the original question automatically preserves spaces, but the comment section does not. To preserve spaces in comments, you need to use the {code} button to enclose code between start and end tags. For the error, Phil's probably right. You need to look at the value in Res_tmp to see what characters are not being translated before using the the %dec() or %int() functions. Tom

Yes
This will throw an error if the value to convert isn’t digits.
Therefore, it should be placed in a monitor block to catch errors.

The value in Res_tmp is the problem.
Do a Dump and check that value.
You’ve converting upper case letters to digits but that insn’t the only thing that can cause errors.

yes Tom ..
i mentioned like this only.
C dsply i_Gen

But it shows the error here ..

C eval i_gen = %dec(Res_tmp : 15 : 0)

the error is ..

A character representation of a numeric value is in error..(C G D F)

Surey…

C     Alpha:Num_tmp xlate     Gen           Res_tmp

Without seeing the value in Gen, there is no way to know what value might end up in Res_tmp. As long as the value can be converted, it should be okay. C DSPLY i_Gen I can't make sense of that statement. The only format that should compile should be:

c                   dsply                   i_gen

But I don't see what good that does. it’s a runtime error… When does it show? What statement throws the error? Tom

This is the code..
FMy_dsp cf e workstn
DAlpha c ‘ABCDEFGHIJLKMNOPQRSTUVWXYZ’
DNum_tmp c ’12594632103109812032011649′
C Z_ADD 0 i_Gen 15 0
C MOVE ‘ ‘ Res_tmp 15
C Alpha:Num_tmp XLATE Gen Res_tmp
C EVAL i_Gen = %dec(Res_tmp:15:0)
C DSPLY i_Gen

Here the Gen is in my Display FIle .. I Declared that usiing +B(15), and changed the field name as Gen ..

Simply, my idea is whatever i gave in that Gen filed (Alphabets) have to converted as Numeric…

Surey..

Hi Tom ..

it’s a runtime error…
A character representation of a numeric value is in error…

this is the error it shows….

Surey..

tomliotta — Sat, 26 Nov 2011 00:29:48 +0000

but it shows error…

What error does it show? When does it show — compile or run-time? How are the variables defined? You show the Num_tmp definition, but you don’t show Res_tmp nor igen. If defined properly, there should be no error.
