Read line from input
|OSWord call||Action||Available on:|
|0||00||Read line from input||x||x||x|
This routine takes a specified number of characters from the currently selected input stream.
Input is terminated following a RETURN or an ESCAPE. DELETE (&7F/127) deletes the previous character and CTRL U (&15/21) deletes the entire line.
If characters are presented after the maximum line length has been reached the characters are ignored and a BEL (ASCII 7) character is output.
OSWORD 0x00 is the only OSWord which return's data in the registers.
|0||2||Buffer address for input|
|2||1||Maximum line length|
|3||1||Minimum acceptable ASCII value|
|4||1||Maximum acceptable ASCII value|
Only characters greater or equal to XY+3 and less than or equal to XY+4 will be accepted. This is useful for forms where you want only digits by setting the minimum to '0' and maximum to '9'
|C=0||Carriage return terminate input|
|C=1||ESCAPE condition terminated input|
