IBM TSO/E REXX User Manual

The SETLANG function can be used in REXX execs that run in any MVS address
space.
Using the STORAGE Function
You can use the STORAGE function to retrieve data from a particular address in
storage. You can also use the STORAGE function to place data into a particular
address in storage.
The STORAGE function can be used in REXX execs that run in any MVS address
space.
Using the SYSCPUS Function
The SYSCPUS function places, in a stem variable, information about those CPUs
that are on-line.
The SYSCPUS function runs in any MVS address space.
Example:
Consider a system with two on-line CPUs. Their serial numbers are FF0000149221
and FF1000149221. Assuming you issue the following sequence of statements
/* REXX */
x = SYSCPUS('cpus.')
SAY '0, if function performed okay: ' x
SAY 'Number of on-line CPUs is ' cpus.0
DOi=1TOCPUS.0
SAY 'CPU' i ' has CPU info ' cpus.i
END
you get the following output:
0, if function performed okay: 0
Number of on-line CPUs is 2
CPU 1 has CPU info FF0000149221
CPU 2 has CPU info FF1000149221
/* ↑ ↑ */
/* | 4 digits = model number */
/* 6 digits = CPU ID */
Using the SYSDSN Function
The SYSDSN function determines if a specified data set is available for your use. If
the data set is available for your use, it returns "OK".
available = SYSDSN('myrexx.exec')
/* available could be set to "OK" */
When a data set is not correct as specified or when a data set is not available, the
SYSDSN function returns one of the following messages:
v MEMBER SPECIFIED, BUT DATASET IS NOT PARTITIONED
v MEMBER NOT FOUND
v DATASET NOT FOUND
v ERROR PROCESSING REQUESTED DATASET
v PROTECTED DATASET
v VOLUME NOT ON SYSTEM
v UNAVAILABLE DATASET
