Extended Macro Syntax

[Charles Pegge]

Using 'procedure' 'sub' 'function' 'as' to improve readability of macros: (The original syntax is still valid)

macro procedure

Code Select Expand

macro procedure mm (a,b,c)
print a+b+c
end macro
'
mm(1,2,3)

macro function

Code Select Expand

macro function mm as int (retv,a,b,c)
retv=a+b+c
end macro
'
print mm(1,2,3)

o2 Macros also support default values:

Code Select Expand

macro function mm as int (retv,a=1,b=10,c=100)
retv=a+b+c
end macro

print mm(2) 'result 112

I've also extended function syntax slightly:

The as specifier can go to the left of the prototype as well as to the right:

Standard function:

Code Select Expand

function ff a(int a,b,c) as long
return a+b+c
end function
print ff(1,2,3)

New alternative:

Code Select Expand

function ff as long (int a,b,c)
return a+b+c
end function
print ff(1,2,3)
