All instructions can be entered in UPPER CASE or lower case, as they are case insensitive.
Leave a space between each instruction, variable or reserved word. Some instructions actually require these spaces; in any case, your programs will be much easier to read if the instructions are separated by spaces.
Each line can only contain one instruction. On the other hand, one instruction may extend over several lines, provided it does not split any lexical items and that the final character in the line is indicated as a "-". This condition does not apply to remarks.
For example:
IF CUSTOMER_BALANCE < 0 OR -
SETTLEMENT_DEADLINE > 35
F_CUSTOMER_NAME:TXT_COLOR = _TXT_COL_RED
END
Instructions must not exceed 5,000 characters in length.
Remarks can be entered on separate lines, with an asterisk (*) at the beginning of the line. Leave a space after the asterisk, to avoid confusion between remarks and reserved words.
A remark can also be included at the end of an instruction line, by preceding the remark with a /*.
For example:
IF COUNTRY_CODE = 'USA' /* Check state code
CALL SELECT_STATE STATE_CODE
END
In short, remarks can be identified by the presence of:
* or /* |
at the beginning of the line; |
/* |
at the end of an instruction. |
For example:
* Check state number
/* Check state number
IF COUNTRY_CODE = 'USA' /* Check state number
