Ways to define STDPARM

You can define the STDPARM parameter file by using one of the following:

The TSO/E ALLOCATE command
Example: The parameter data to be passed to BPXBATCH resides in the MVS™ sequential data set TURBO.ABC.PARMS.
```
ALLOCATE DDNAME(STDPARM) DSN('TURBO.ABC.PARMS') SHR
   
```
A JCL DD statement. To identify a z/OS UNIX file, use the PATH operand and specify PATHOPTS=ORDONLY.
Example: The parameter data resides in the z/OS UNIX file /u/turbo/abc.parms.
```
//STDPARM DD PATH='/u/turbo/abc.parms',PATHOPTS=ORDONLY
```
Example: The BPXBATCH parameter data resides in member P1 of the MVS PDSE TURBO.PARM.LIBRARY.
```
//STDPARM DD DSN=TURBO.PARM.LIBRARY(P1),DISP=SHR
   
```
An JCL in-stream data set
The BPXBATCH parameter data immediately follows the STDPARM DD statement. Trailing blanks are truncated for in-stream data sets, but not for other data sets.
Example: The following invokes the echo shell command.
```
//STDPARM  DD *
SH echo "Hello, world!"
/*
```
Example: Consider the following shell script called myscript.sh. This shell script writes to stdout the first three arguments that are passed to it.
```
#!/bin/sh
#Write arguments 1 through 3 to stdout
echo $1
echo $2
echo $3
```
The following is one way to define STDPARM to run the script:
```
//STDPARM  DD *
SH /myscript.sh AAAA BBBB CCCC
/*
```
Here is another way, placing the arguments on separate lines:
```
//STDPARM  DD *
SH /myscript.sh AAAA 
BBBB 
CCCC 
/*
```
Result: Both of these STDPARM definitions produce the following output:
```
AAAA
BBBB
CCCC
  
```
SVC 99 dynamic allocation, if you are running BPXBATCH from a program
