General rules and Syndax

General Rules

The structure of the language is very simple. Like a "simple basic". When writing AutoScript the following rules apply.

Letter case matters, for example New and NEW are different variables.

Commands never continue to next line.

Arrays of one dimension are permitted.

We do not have declaration of variables. The appearances of variables into the code declare automaticaly the variables. If a variable appears later as an array variable then converts to an array having as dimension the greatest index.

First element of an array has index of (1) i.e A[1].

All variables are of variant type. They behave relatively on the context they used. For example:

Functions must be calculated in a separate line. For example instead of:

a = 10*value(x,z) + 10

write

a = value(x,z)

a = 10*a + 10                

Syntax

We give the vocabulary of AutoScript by using small examples

if … then

for … next

for i = 1 to 100

   A[i] = i * 10

next

or

j = 2

for i = 1 to 100 step j

   A[i] = i * 10

next

or

for i = 1 to 100

   A[i] = i * 10

   if (A[i] = 30) then

      i = 100                 

   endif

next

proc … end

proc showmessage( msg )

      call message("the message is :" , msg)

end

fun … end

fun final_value(a,b,c)

     result = a + b + c        

end

call

call showmessage(msg)

or

call showmessage("new message")

return

if ( stop1 = True ) then

  return                              

endif

start_sql … end_sql

start_sql "query_name" "KOSMOS"

         SELECT *

         FROM

           PRODUCTS

end_sql

in the above lines of code we declare the query. The execution takes part by calling the procedure RunEmbSQL
