How to write an apostrophe using msgNotify ?

The title says it all. How do i write an apostrophe in KRL, I'm using MsgNotify to write the message "Tool can't open." but whenever i write > ' < workvisual takes it as the start of a new CHAR.

The easy solution is to write a better message that dosen't use "can't" but it got me curious.

Here is an example:

DEF ROBOT_STOP()

oROB_EMNE_FEJL=TRUE

msgnotify("Tool can't open")

BRAKE f

Halt

oROB_EMNE_FEJL=FALSE

END
