====== READSPEC Command ======

READSPEC,<SpecFile>,<numLines>,<Line1> … <LineN>

Reads a spectrum file into a line object for plotting. 

  * SpecFile – Full path of the spectrum file to be read
  * numLines – number of data columns to be read from the file
  * Line  - Line Reference Number for each line object to be read
 
**NOTE:** Line objects in ACS SASSI are read from the columns in a data file. For TFI, TFI, TFD, and RS files, the frequency column should not be counted in the <numLines> argument.  For example, an RS file has a column for frequency and a column for acceleration. In this case, <numLines> is 1 because there is only one column of data to be read into a line object for plotting.
