opcode specifies operational options such as pre-load, output vs. input, or format conversion:
Symbol |
Value |
Description |
|---|---|---|
INFOP_EDIT |
&h0000 |
Normal operation (input). Field is cleared first. |
INFOP_PRELOAD |
&h0001 |
Like INFOP_EDIT (0) except contents of entry are preloaded into the field and displayed before input. Note that for codes d, Y, and N (Y/N), entry overrides the standard default only when entry is non-null. Also note that leading fill characters in R and Z fields, and trailing blanks in all field types will be stripped to simplify editing. You can, however, force it to keep one or more trailing blanks by supplying them as chr$(160) (which is a blank with the eighth bit set).This can be useful in conjunction with the ")" code |
INFOP_DISPLAY |
&h0002 |
Format and output contents of entry. (No input) |
INFOP_SIMPLE |
&h0004 |
Speed and cursor motion optimized version of opcode 2; assumes screen already clear. Relevant only for text mode. |
INFOP_FORMATTED |
&h0008 |
Like INFOP_EDIT (0) except returns entry formatted. |
INFOP_PRELOAD + INFOP_FORMATTED |
&h0009 |
Like INFOP_PRELOAD (1) except returns entry formatted. Note that you must de-format the field (somehow) between successive opcode=9 calls to the same field. |
INFOP_PRELOAD + INFOP_DISPLAY |
&h000A |
Like INFOP_DISPLAY (2), except returns entry formatted. |
INFOP_FMTONLY |
&h001C |
Format conversion only. Takes entry unformatted and returns it formatted. |
INFOP_READONLY |
&h0021 |
Read-only input mode. Field loaded with entry, but cannot be changed. Exitcodes however are still possible. This might be useful in a case were you want to allow a user to review previous entry fields, but only change them by first hitting some kind of special exitcode and then entering a password. This has the same effect as type |r. |
