The FDL compiler imposes a number of constraints on the
sequence in which commands are coded. The form name must
come first. Only one form orientation is permitted, and fonts
and boxes must be implicitly or explicitly defined before they are
referenced by TEXT commands. After that point, the sequence is
not significant to the compiler. However, it is worthwhile to
develop a sequence while debugging or making changes to a
form. Use a method of sequencing commands similar to the
following:
• Horizontal and vertical lines
• Boxes (if needed)
• Text
• Logo placement
• Shading.
Because FDL keywords can be abbreviated to the first three
characters, and because certain two-character keywords can be
interpreted in more than one way, the following known
ambiguities exist:
• IN (preposition) is interpreted as IN (inch). For example:
TEXT 1 IN BOX...;
Also,
TEXT SPACED 1 IN BOX...;
The keyword IN is interpreted as INCH, while the required
keyword IN (preposition) is detected as missing and an error
message results. The solution to this situation is to write the
following:
TEXT 1 IN IN BOX...;
TEXT 1 INCH IN BOX...;
TEXT 1 DOTS IN BOX...;
• FMTn cannot be abbreviated.
