Some on this list may have written programs for preparing data in "alpha" 
or ascii format.  To understand about sac file formats, I suggest you 
spend time with the sac users manual at 
<http://www.iris.edu/manuals/sac/manual.html>.  Instructions like the 
following may be helpful:

Sample Alphanumeric Data File

The header section and first five lines of the data section of a sample 
SAC alphanumeric data file is shown below. You can reproduce this file 
(with the entire data section) on your system by executing the following 
commands:

u: FUNCGEN SEISMOGRAM
u: WRITE ALPHA TEMP1

You can then convert this alphanumeric file to a binary one and read it 
into SAC with the following commands:

u: CONVERT FROM ALPHA TEMP1 TO SAC TEMP2
u: READ TEMP2

(cut and paste from the manual)
