Hi all,
I have a small problem with Turbo Pascal 3.3f. Is the Pascal Val function supported?
(to convert a string value to an integer)
The compiler stops with an error msg.

Stupid question, being a total (Turbo) Pascal noob, but doesn't it have anything to do with case sensitivity? Maybe val() works?

Pascal language is case insensitive 
About the problem with VAL function, I've never used Turbo-Pascal for MSX  |

I think you can use it. But is not a FUNCTION, is a PROCEDURE.
VAL Convert String to Number pp 70
Syntax: Val (StrVar,NumVar,Code) ;
Type: Integer or Real
Form: Procedure
Purpose: Convert string value of StrVar to a numeric value in NumVar.
Notes: NumVar is type Intger or type Real. Code is any error code.
No errors occurred if Code = 0.
----------------------------------------------------------------------------
Usage:
CONST
StrVar : String [4] = '1234' ; { String value of 1234 }
VAR
Code : Integer ; { Error code }
IntVar : Integer ; { Integer variable }
RealVar : Real ; { Real variable }
BEGIN
Val ('$FFFE',IntVar, Code) ; { '-2' }
Val ('1.123',RealVar,Code) ; { '1.1230000000E+00' }
Val (StrVar, IntVar, Code) ; { '1234' }
END.
