MultiLoad is going to need to know the structure the INPUT 
flat file. Use the .LAYOUT command to name the layout.
It is used to designate the starting location for this data 
based on the previous fields length. If you are listing 
fields in order and need to skip a few bytes in the record, 
you can either use the .FILLER (like above) to position to 
the cursor to the next field, or the "*" on the Dept_No 
field could have been replaced with the number 132 ( CHAR
(11)+CHAR(20)+CHAR(100)+1 ). Then, the .FILLER is not needed

In .IMPORT command in MLoad  we have a option to give 
record no. from which processing should begin. ie. ‘FROM m’
‘m’ is a logical record number, as an integer, of the 
record in the identified data source where processing is
to begin. You can mention ’m’ as 2 and processing will 
start from second record.

THRU k and FOR n are two options in the same MLoad command, 
functions same towards the end of the processing.
