String Variables

Basics

String variables have $ sign at the end:

mystring$

To asign a string to the variable we use:

mystring$ = 'This is a text'

Note: we use ' not " character

To put a ' character (Like in Oscar's) use \'

Example:

mystring$ = 'This is Oscar\'s project'

You can add backslash at the end of a string by using \\
path$ = 'c:\mydir\\'
will be displayed as c:\mydir\

Strings can use operator plus (as many as you want):

a$ = 'MMB '

mystring$ = a$ + 'is cool'

CHAR function

You cannot mix numerical and string variables.

To convert a numerical variable to string we use CHAR function

• alue = 2.45

mystring$ = CHAR(value)

VAL function

To convert a string variable to numerical variable we use VAL function

mystring$='1.222'

• alue = VAL(mystring$)

String in IF-END command

We use similar syntax to numerical variables:

if (mystring$='yes')

....

end

or

if (mystring$<>'yes')

...

end
