| 30 | Possible Additions:
|
---|
| 31 |
|
---|
| 32 | hmiINIAddItemDecimal( ) adds new item w/decimal
|
---|
| 33 | hmiINIAddItemQuery( ) adds new item w/query Yes/No
|
---|
| 34 | hmiINIAddRawString( ) adds new raw string
|
---|
| 35 |
|
---|
| 36 | Error Checking:
|
---|
| 37 |
|
---|
| 38 | allow TABS to be skipped as "White Space" in addition to spaces so
|
---|
| 39 | that editors that use tabs will work also.
|
---|
| 40 |
|
---|
| 41 | allow String functions to support lists with comma (,) seperators
|
---|
| 42 | like the decimal functions do.
|
---|
| 43 |
|
---|
| 44 | allow location functions to be case sensitive or insensitive
|
---|
| 45 |
|
---|
| 46 | get rid of compiler dependent stuff like memcpy, stricmp
