Find multiple patterns on multiple lines and concatenate output

I'm trying to parse COBOL code to combine variables into one string. I have two variable names that get literals moved into them and I'd like to use sed, awk, or similar to find these lines and combine the variables into the final component. These variable names are always VAR1 and VAR2. For example, I'd like to find these:
Code:
 
MOVE 'LIT1'  TO VAR1
MOVE 'LIT2'  TO VAR2

...and print this:
Code:
 
LIT1LIT2

This could happen multiple times in one file. For example, if these were the entries:
Code:
 
some junk
MOVE 'LIT1'  TO VAR1
other junk
MOVE 'LIT2'  TO VAR2
more junk
more junk
MOVE 'LIT3'  TO VAR1
MOVE 'LIT4'  TO VAR2
junk again
MOVE 'LIT5'  TO VAR1
more junk
more junk
MOVE 'LIT6'  TO VAR2
junk

I'd like to print this:
Code:
 
LIT1LIT2
LIT3LIT4
LIT5LIT6

MOVE(7) 							   SQL Commands 							   MOVE(7)

NAME
MOVE - position a cursor SYNOPSIS
MOVE [ direction { FROM | IN } ] cursorname DESCRIPTION
MOVE repositions a cursor without retrieving any data. MOVE works exactly like the FETCH command, except it only positions the cursor and does not return rows. The parameters for the MOVE command are identical to those of the FETCH command; refer to FETCH [fetch(7)] for details on syntax and usage. OUTPUTS
On successful completion, a MOVE command returns a command tag of the form MOVE count The count is the number of rows that a FETCH command with the same parameters would have returned (possibly zero). EXAMPLES
BEGIN WORK; DECLARE liahona CURSOR FOR SELECT * FROM films; -- Skip the first 5 rows: MOVE FORWARD 5 IN liahona; MOVE 5 -- Fetch the 6th row from the cursor liahona: FETCH 1 FROM liahona; code | title | did | date_prod | kind | len -------+--------+-----+------------+--------+------- P_303 | 48 Hrs | 103 | 1982-10-22 | Action | 01:37 (1 row) -- Close the cursor liahona and end the transaction: CLOSE liahona; COMMIT WORK; COMPATIBILITY
There is no MOVE statement in the SQL standard. SEE ALSO
