Macro variable resolves the same value in a do loop

[jakarman]

As your SAS session is needing to be segregated form the running sources possible ruining your session or each other, there are several solutions.

It is possible to run asynchronously (all jobs starting same moment) or serial (synchronously, waitfor). Serial processing will take longer but is easier to understand.

1- one of the many X-cmd usages. statement,  Piping (serial),  datastep/macro

    systask is having more options: SAS(R) 9.3 Companion for UNIX Environments

    pipe is forcing you to wait and you, advantage you can see more of the OS-messages. SAS(R) 9.3 Companion for UNIX Environments

2- usage of mp-connect

    Watch the !sascmd (the exclamation is used for the OS value ot that variable) you could use the same using a x-cmd
