The Capitals' "franchise" can look forward to a long stay in Washington. Center Guy Charron, a 74-goal socorer over the past two seasons and nicknamed the "franchise" because he has been carrying the Capitals' scoring load on his back much of the time, agreed to a long-term contract yesterday.

Charron, entering the option year of the pact he signed on coming here from Colorado in 1976, had been earning $85,000 a year. He is believed to be getting about $125,000 under the new arrangement.

"We're delighted, of course," said General Manager Max Mcnab. "He has been our talent leader for a couple of years and this sets him up as a Washington resident for a number of years."

Publication of National Hockey League salaries in March indicated that Charron was considerably under-paid in relation to others around the league. He had no complaints, however.

"You can't be jealous about another guy and his salary," Charron said at that time. "When you negotiate, you accept the terms. You fight for what you get, you try to get what you deserve and then you are satisfied until next time."

Joining the ranks of the satisfied with Charron was defenseman Gord Lane, who presumably received a slight raise over his $50,000 salary of a year ago.

The first formal occasion as training camp opened here last night was a team meeting, at which McNab and Coach Tom McVie delivered pep talks and the club's Ottawa-based fitness team discussed nutrition and weight training.

Today will be devoted to physical testing, with the annual mile run scheduled for 2 p.m. in Hershey Stadium. At 4 p.m. the players will be warned about gambling and drugs by Frank Torpey, NHL director of security. Two-a-day workouts on the ice start tomorrow.
