OWBasic 4.4

Changes in OWBasic 4.40 Beta 3:

• Compiler Directives
• LOCAL for declaring local variables
• Function and procedure pointers
• FILEFIND searches for a file by its name
• FILELABEL$ returns file label
• DRAWSTRING can draw a string right aligned
• DUP$ () multiplicates a character
• TOUCH! has four optional coordinate box parameters
• TCHINSIDE! checks whether TCHX and TCHY are inside a coordinate box
• TCHSET sets the touch panel status

• Initialized string constants

CONST s$=("one", "two", "three")

• String literals can contain an escape sequence that defines a character by its hexadecimal value
• BREAK and CONTINUE are possible in loops
• Functions can be called as procedures (without using the return value)

Changes in OWBasic 4.40 Beta 4:

• Constant expressions are evaluated at compile time now
• The constant functions VARDEF and PROCFUNCDEF check whether a variable/procedure/function is defined
• NOT is an unary operator available for Integer (bitwise negation) and Boolean (logical negation)
• Constants can be assigned a value at compile time
• The Integer constant PVMODEL contains a value that represents the PV model

Changes in OWBasic 4.40 Final:

• INPUTI, INPUTF and INPUTS allow the user to edit the value of a variable
• The global variable FBBSIZE contains the size of the binary filebuffer
• multi-line comments possible with "/*" and "*/"
• The program code amount was increased (5136 -> 5392)

Changes in OWBasic 4.41:
