RP: Haw to Convert ASCII CCSID 61952 to EBCDIC 037 follow up !!

I have now managed to remove the 2 Hex byte in start.
It seems that VARYING set lengt of the Variable in start of this.
But then I get NULL char at the end. Haw can this be removed.

X'61D5C5E3C4C1E3C161A683A76D86A3974B899589404040404040404040404040400000
000000000 > 254 zero.

The Code I have added is this ex.

D MeFile S 254a

MeFile = %subst(MyFile : 1 : ChkFileLen);
CALLP NETPPECL(SBMPGM : SBMLIB : JOBDFILE :
JOBDLIB : JOBQ : JOBQLIB : SBMUSER : MeFile);

I cant see any way in CL to trim them ither in RPG ??

I have now get the string with file name created in IFS.
But the file name have some strangers hex char in the start of varible

MyFile. ??

Here is my sample exit program. What can I do to remove the starting

hex char. ex. x'0028' it look like it has some form >off lengt of the
variable.

Is this normal when setting variable VARYING.
I can se this in the CL program that i Call.
