C2D function in rexx not giving me correct result.

Hi All,
I am using a rexx routine to get the sum of a particular numeric field for all the records present in a file.The numeric field appears in the input file at pos 55-64.
suppose my input file has 2 records having nos
1011621000
1011621000
in 55-64 pos then the sum should be 2023242000

I am using the below code
ADDRESS TSO
"ALLOC FI(DD1) DA('F3674AO.PDTEST.OUT.REC3.IN') SHR REUS"
"ALLOC FI(DD4) DA('F3674AO.PDTEST.OUT.REC3.OUT') SHR REUS"
"EXECIO * DISKR DD1 (FINIS STEM A."
SUM = 0
DO I = 1 TO A.0
J.I = SUBSTR(A.I,55,10)
SUM = SUM + C2D('J.I')
END
"EXECIO * DISKW DD4 (FINIS STEM J."
SAY 'SUM' SUM

I know somewhere the C2D function is wrong and thats why I am not getting the proper result.Can anybody tell me how to achieve the same result.

What exactly is it that you believe the C2D function does?

C2D is the decimal representation of the binary character string.Maybe I am wrong in my concept to use that for my rexx.
Could you please help me out for the same problem by providing the sample rexx code.

In fact, if you add within the loop:

SAY 'DATATYPE OF 'J.I' IS 'DATATYPE(J.I)

you will see that J.I is already a number and there is no need for conversion.

C2D is mostly used to transform a character into it's numeric value:

C2D('A') returns 193 and C2D(1) returns 241

similarly, C2X('A') returns 'C1' (a 2 chars string)
