Labels & numerics

[riv503ca]

Hi All! When writing programs with the OSHONSOFT Basic Compiler
what are the rules governing LABELs ?

What are the rules governing numerics and ASCII characters?
For example do we use $55 or 0x055 for hex? Binary #s? Decimal #s?

There is not much in the reference manual on these subjects.

hi,
Is this the info that you are asking for.?

Const pi = 314
Const beta = 123

Dim abit As Bit
Dim abyte As Byte
Dim aword As Word   
Dim arry(5) As Byte

abit = 0
abit = 1
abit = 0x01
abit = %1
abit = %0
abit = 1h
abit = True
abit = False

''abyte = &13  'not allowed
''abyte =.13  'not allowed
''abyte = #13'not allowed

abyte = %00010011  'binary notation
abyte = 13h  'hex notation
abyte = 0x13  'hex notation
abyte = 13  'decimal
abyte = arry(0)
abyte = beta  'constant

aword = %0000000000010011  'binary notation
aword = 1213h  'hex notation
aword = 0x1213  'hex notation
aword = 1213  'decimal
aword = arry(0)
aword = pi  'constant

Good afternoon, Mr. Gibbs,
Thank you for the info.
As to LABELs:
How many chars are allowed (label length)?
What Chars are not allowed?
Also, is $55 a correct hex format?

hi,
$55 is allowed, it represents 55hex.

I will look thru the documentation to check regarding chars and length.

EDIT:
The max label length is 32 characters.
I would suggest that you write a simple Basic program and try the 'characters' that you would like to use, in order to check their acceptance.
If you do, please post your results.

Dim a1234567890123456789012345678901 As Byte  'the 32 len appears to be the limit

dummy:
a1234567890123456789012345678901 = 13h
Goto dummy

End
