all about strings

[Giancarlo]

Hello,
pressing the softmenu Cmds/Strings menu when Programming, i can access only to string commands like:
ASC
LOWER
STRINGFROMID
ROTATE
MID
UPPER
RIGHT
INSTRING
STRING
EXPR
DIM
CHAR
LEFT
REPLACE

I am missing, in the same menu the following commands to handle strings:
SUPPRESS
INSERT

Are there other missing commands?
Is it possible to insert them in the same menu in a new firmware release?

thanks

Giancarlo
