Hi to all,
it seems to me very strange but compiling following IS code:

string 3Gparameter;
3Gparameter = "";

will produce a compiling error:
functionX.rul(183): error C8008: '3' : identifier expected
functionX.rul(196): error C8079: '3' : invalid statement

Didn't a string start with a number?

Thanks to all, ciao

I have come across that as well Gronchi. I solved it by renaming the variable with a name that does not start with a numeral. I did try and find the rules for naming variables under IS Pro, but couldn't find it in 10 mintes of looking.

Such a syntax restriction is pretty standard, and as Xitch13 stated, it's easy enough to workaround.

Check this out from the Language Reference Guide. Page 6


Identifiers are the names that you create to denote constants, variables, and functions in your script.
Observe the folowing syntax rules when creating identifiers.

1. An identifier may be of any length, but only the first 63 characters are significant.

2. The first character of an identifier must be alphabetic (a-z,A-Z) or an underscore (_).

3. The remaining characters may be alphabetic (a-z,A-Z), numeric (0-9), or an underscore (_).

4. Each identifier must be unique. Be careful not to create an identifier that is a reserved work in InstallScript.

in addition to the quoted rules, it may be helpful to start an identifier with a character that tells about the type, like s... for string an n... for numeric variables.
You may even use sv... for variable strings and sz... for literals and so on.
