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

NAME
nd - Tiny little command line WebDAV interface SYNOPSIS
nd [options] url DESCRIPTION
nd provides a simple command line interface to the RFC 2518 (WebDAV) server. If no option is specified, HTTP GET command is issued and writes response data to the standard output. The options are as follows: -c dest_url COPY url to the dest_url. Use lock token if -t is specified. -f Force override the content even when the MOVE or COPY target already exits. -v View property information of url by PROPFIND. With -g option, only the specified property is displayed. -p file PUT file content to the url. Use lock token if -t is specified. -g name Specify the property name for -v option. -e name=value Edit the property with name to value using PROPPATCH . -N namespace-url Specify the property namespace URL for -e or -g option. -P file POST file content to the url. -T is used for the Content-Type. -T content_type Use content_type as a Content-Type field value of the POST request. Default is `application/x-www-form-urlencoded'. -d DELETE url. Use lock token if -t is specified. -l LOCK url. Use -o as owner, -s as scope, -i as timeout. -o owner Specify lock owner. Default is USER environment variable. -s scope Specify lock scope (`exclusive' or `shared'). Default is `exclusive'. -i timeout Specify lock timeout interval. Default is `Infinite'. -u UNLOCK url. -t option is required. -t token Specify the lock token. -r Set command execution `Depth' as `Infinity'. -a realm Specify authentication realm. -A realm Specify proxy authentication realm. -k MKCOL url -m dest_url MOVE url to the dest_url. Use lock token if -t is specified. -S Print output using s-expression. ENVIRONMENT VARIABLES
http_proxy, HTTP_PROXY Specify HTTP proxy. USER When manipulating a lock without an explicit owner option, the value of USER is used to set the owner of the file lock. BUGS
A maintainer of the Debian package has implemented Digest authentication on top of the original software. However, the upstream source uses the nanoHTTP code from libxml2 to implement the HTTP transport. Due to properties inherent in that code for detecting and following redi- rected target sites, there is no way to pull out the new address in order to insert it into the hashes necessary for the Digest method. Nd will therefore incorrectly answer with 'Bad request' to any method call aimed at such sites. Using the correct logical name for the target will, however, produce a correct response from Nd.
