[SAC-HELP] concatenating blackboard variables

[Carmen del Fresno Rodríguez-Portugal]

I have been using SAC for about four years under SUN-Solaris without any
problem but I have recently had to migrate to work with a Linux-Suse and
I installed SAC v101.0. I am having some problems when I try to
concatenate blackboard variables.

For example, if I run this easy macro:

do file wild *bhz
setbb base ( BEFORE "bhz" $file )
message "base is %base%"
r %base%bhz %base%bhe %base%bhn
synch
enddo

Everything works fine until the 4th line, where I get a segmentation
fault. 

Any ideas?
Thank you very much,
Carmen
