BLDCLLSTR

["Alan G. Campin" <agc@xxxxxxxxxxxxxxxxxxxx>]

There was a lot of discussion recently on this forum of the problems
that occur when you submit strings using CL and the SBMJOB command and
the string variables are longer than 32 characters.

 

At the time, I indicated that I was going to build a command that would
build the CALL strings without the compression and I have finally
finished. 

 

The command is called BLDCLLSTR and below the line is from the
readme.doc included in the zip. 

 

Note that the resulting variable gets passed through RQSDTA and is
limited to 3000 characters. 

 

I have created a zip containing a save file @ V5R2M0 and the source in
text for those who want to modify to work below V5R2M0. Only one
program.  

 

If you would like a copy, please send me an e-mail at

Thanks.

Normally, if you build a CALL command using SBMJOB in CL and if you have
a string variable, the variable will be trimmed to the length of the
data in the string. 

 

For example, if you have 50 character variable with:

 

'My Sister Sam                                   '

 

what gets passed to the new job is

 

'My Sister Sam'

 

and if the receiving program is expecting 50 characters, you get
garbage.

 

This problem does not occur if the string is less than 32 characters
because IBM always passes string variable with a minimum of 32
characters. The problem only occurs if you try to pass a string longer
than 32 characters.  

 

BLDCLLSTR just builds the CALL string without the blank compression. The
resulting command is then sent through on the RQSDTA parameter.

 

This is from test program TESTCMDP.

 

DCL        VAR(&QUOTE) TYPE(*CHAR) LEN(1) VALUE('''')                  

 


CHGVAR     VAR(&VARIABLE3) VALUE(&V92)

                                 

BLDCLLSTR  PGMANME(AGC/TESTCMDP2) PARMS((&QUOTE || +         

              &VARIABLE1 || &QUOTE) (&QUOTE || +              

              &VARIABLE2 || &QUOTE) (&QUOTE || +              

             &VARIABLE3 || &QUOTE)) RTNSTRING(&RTNSTRING)    

 

SBMJOB     JOB(TESTIT) RQSDTA(&RTNSTRING) LOG(4 00 +         

                          *SECLVL)         

 

I just use the trick of putting quotes around the variables so that I
receive the true length.
