Level 2 Help for TRANSECT

Input file name. The file may be BYTE, HALF, FULL, or REAL; if multichannel,
it may be BIL or BSQ.  BIP is not presently implemented.

This is the line and sample of the starting point of the transect (or DN 
profile). The value at this location is plotted at zero on the x-axis.

This is the line and sample of the end point of the transect. The value at
this location is plotted as the rightmost value along the x-axis.

If the input dataset is multichannel, BAND designates which band is to be
plotted. The default is Band 1.  

YAXIS indicates the full scale limits of the y-axis. If defaulted, the program
chooses limits that completely span the range of the data plotted. 

The user may place a line of annotation up to 80 characters in length on the 
printed plots. This annotation does not appear on the screen, and, if a printed
plot is not requested, the value of TITLE is not used.

When printing on the laser printer, the user may place a label on the X-axis.
The label may be up to 40 characters in length, and does not appear on the 
other plot media. The default is "Relative Pixel Position".

When printing on the laser printer, the user may place a label on the Y-axis.
The label may be up to 40 characters in length, and does not appear on the 
other plot media. The default is "DN Value".

If the keyword PRINT is given, the pixel locations and values are printed to
the terminal and session log.  Otherwise, only a plot is made.
