Yes, but you could concatenate a string of special characters to the end of the
string and scan for that. By using the *TCAT concatenation operation, you
remove trailing blanks first.
The following example CL demonstrates this. I have used two tilde characters
as the scan string, but it could be anything:
PGM PARM(&STRING)
DCL VAR(&STRING) TYPE(*CHAR) LEN(80)
DCL VAR(&TEST) TYPE(*CHAR) LEN(81)
DCL VAR(&POS) TYPE(*DEC) LEN(3 0)
DCL VAR(&MSG) TYPE(*CHAR) LEN(3)
CHGVAR VAR(&TEST) VALUE(&STRING *TCAT '~~')
CALL PGM(QCLSCAN) PARM(&TEST X'081F' X'001F' '~~' +
X'002F' '0' '0' ' ' &POS)
CHGVAR VAR(&POS) VALUE(&POS - 1)
CHGVAR VAR(&MSG) VALUE(&POS)
SNDMSG MSG(&MSG) TOUSR(*REQUESTER)
ENDPGM
Note, that in the example you will have to call the program via a command or
pad out the string parameter otherwise the issue with CL parameters greater
than 32 characters arises:
CMD PROMPT('Test CL Scan')
PARM KWD(STRING) TYPE(*CHAR) LEN(80)
All the best
