[SAC-HELP] SAC error message "remove this function:"

[LeRoy M. Dorman]

I am trying to produce a sac file containing a sequence of sawteeth.

The macro file is:

*this is a SAC macro to generate a sawtooth, approximating a
*stick-slip source.
funcgen line -2 1. npts 50 delta 0.01
qdp off
*plot
*pause
funcgen impstrin 100 200 300 400 500 600 700 800 900 1000 1100 1200 1300

convolve master 1
plot
write sawtooth.sac

Executing this macro in SAC produces the following error.

remove this function: src/co/zmemad()

this diagnostic appears upon execution of the convolve command.

I tried removing the files zmemad* from the SAC src/co directory, but
that action had no effect.

So what am I doing incorrectly (or not understanding about the convolve 
directive)?
