- %edi is the input text where termination character is excluded

- %sev is the EDI port (sub-event)

• Operator macros

- %scutc(string,start-pos,lenght)

• Extract substring by byte (character) position
• Example: %scutc(0123456789,2,3) returns 234
• Example: %scutc(%edi,4,3) returns 3 characters from the input string, starting from char 5

- %scutf(string, delimiter, field-no)

• delimiter is a single char, possibly escaped. Example: Tab= \t ‘,’ = \,
• Optionally followed by + sign to indicate that more than one delimiter character is allowed between fields
• field-no is a integer number, counting starts from zero!
• Example: %scutf(%edi, +,3) extract field number 3; fields separated by any number of spaces
• Example: %scutf(%edi,\,,3)extract field number 3; fields separated by commas

- %sscan(string, search-string)

• Scan for string, extract rest of string after first match
• Example: If %sscan(%edi,connect) Check if text has the string “connect”

- %scmp(string1,string2)

Compare strings. Return “1” if equal, empty string if not

• Temporary variables

-Temporary variables (strings), numbered 0 to 9

-Lives only within the action string

-Set temporary variable: TMP 0 "<string>"

-Read temporary variable: %tmp(0)

• The rules below will allow you to issue commands to EDI port like this:
• connect,101,103

-Generates internal <br\>command $CALL <br\>L101 L103

• disconnect,101,103
