NAME

lset - move data into random file buffer

SYNOPSIS

lset StrVar = StrExpr

DESCRIPTION

Lset places data into a random file buffer in preparation for being moved into the random file with a put statement.  StrVar is the name of a variable that was defined in a field statement.  StrExpr is a string expression containing the data to be placed into the field associated with StrVar.  If StrExpr is shorter than the field associated with StrVar, the data is inserted into the field, left-justified and padded on the right with spaces.  If StrExpr is longer than the field, the data string is truncated on the right and inserted into the field.  Numeric values must be converted to binary strings with mki$, mks$ or mkd$ before using lset. 

EXAMPLE

	 10 open "addrph" as #1 len = 150
	 20 field 1, 35 as n$, 80 as a$, 12 as ph$
	 30 lset n$ = "Basmark Corporation"
	 40 lset a$ = "1717 East Ninth Street, Cleveland, Ohio"
	 50 rset ph$ = "800-555-1212"
	 60 put 1
	 70 close 1
	 80 open "addrph" as #1 len = 150
	 90 field 1, 35 as n$, 80 as a$, 12 as ph$
	100 get 1
	110 print n$
	120 print a$
	130 print ph$
	140 close 1

Lines 30 through 50 put information into the buffer, and the put statement in line 60 writes the buffer to the file.  Line 100 reads the buffer back from the file and lines 110 through 130 display the contents of the buffer.
