That problem has gone. For future reference, I am using version 2.47. The problem I'm having now is this. I have perfect radio communications between 2 16F877A's, at both short and long range, but I'm not having much success transmitting and then receiving variables.

My TX line is :
SEROUT2 PORTc.2,16780,[((id<<6)+(rhtc/100<<3)+(temp/100))]

which seems not to be a problem

my RX line is

SERIN2 PORTc.4,16780,250,programstart,[str myvar\6]

but I don't get what I send. I'm sure there is a glaring error somewhere, but when I hserout myvar I get numbers, but not what I sent
