Remove characters from string

[codGmer]

Hello,

I want to remove some characters from a string in GSC but i can't seem to figure out what kind of function i need to use.

onPlayerSpawned()
{
	self endon("disconnect");

	for(;;)
	{
		self waittill("spawned_player");
		self thread noTube();
	}
}

noTube()
{
    self endon("death");
    self endon("disconnect");

    for(;;)
    {
        if(isSubStr(self getCurrentWeapon(), "_gl"))
        {
        	self.ownWeapon = self getCurrentWeapon();
        	self.ownWeapon = **Remove _gl from string**("_gl", "");//here
			self takeWeapon(self.ownWeapon); 
			self giveWeapon(self.ownWeapon, 0, false );
			self switchToWeapon(self.ownWeapon, 0, false );
        }
        wait 0.05;
    }
}
