Can Capslock mimick the use of shift

I am using lightweight Linux, with Xorg, an minimal xbase-client for the only purpose to launch specific program on remote site. These programs used by lambda users works well with a single default. When used on laptop computer with no digit-keypad the only way to type digits on entry fields is to use the upper line of the keyboard. The thing is that with an English/US keyboard there is no problems, but with a French keyboard if I type the keys 123 with shift I got 123, with nothing pressed I get &é" and with capslock pressed I get &É". But for most user when they are entring digigs they are used to set capslock on and directly type the digits. Which, in this case is not effective. Is there a way to have capslock do the same as keeping shift while typing?
