Command
- EVAL_TEXT <string variable>
Evaluate any variables stored in a text variable and save the resulting text back to the variable.
- You need to use this command if you are building up a string variable using the same variable with different values.
- Any variables used inside the contents of a string variable are only converted from numbers to text when the string variable
- is used to write to a file, passed to another macro or displayed on a dialog.
Parameters
- <string variable>
- a string variable, for example a$
Example
- i = 123
- a$ = "i = %i"
- i = 246
- a$ = a$ + " and now i = %i"
- Message a$ ( this will display the text "i = 246 and now i = 246"
- i = 123
- a$ = "i = %i"
- EVAL_TEXT a$
- i = 246
- a$ = a$ + " and now i = %i"
- Message a$ ( this will display the text "i = 123 and now i = 246"
- For an example macro see Process_Data
