INFLD is a powerful and flexible field-level input and display routine, operating in both text and GUI modes. In GUI mode, it takes on the form of a edit control, combo box, date/time picker, or up/down (spinner) control, depending on the parameter options. INFLD's GUI mode is generally application-compatible with text mode, but of course requires either A-Shell/Windows or ATE. INFLD is also used internally to implement the A-Shell dot-prompt, the VUE command line, and INMEMO.

History/compatibility note: Originally developed as an upward-compatible replacement for the native AMOS subroutine INPUT.SBR, INFLD was sold as a standalone product under AMOS. The A-Shell implementation is upward compatible with the AMOS version, but adds many additional capabilities, most notably the GUI extensions.

In addition to the Update Notes mentioned above, the documentation is divided into three sections: Parameters, INFLD External Parameters, and INFLD Miscellaneous Topics.

Syntax and Parameters

xcall INFLD, row, col, xmax, xmin, type, entry, inxctl, parentid, opcode, exitcode, timer, cmdflg, defpt, maxpt, funmap, setdef, infclr, hlpidx, maxchrs

Parameter	Type	I/O	Description
row	Num	in	Row for input
col	Num	in	Starting column.
xmax	Num	in	Maximum size (width; see maxchrs).
xmin	Num	in	Minimum number of characters to accept. Note that if the O (optional) type code is used, the minimum is only in effect if at least one printable character is entered.
type	String	in	Codes specifying types, formats, etc.
entry	String	in/out	String field contents sent and returned in
inxctl	→	out	(String,1 or F6) Special exit codes compatibile with INPUT.SBR
Parameters above are required; those below are optional.
parentid	→	in	(String or Num) If zero, multiplies (row) by two
opcode	Num	in	Used to specify pre-load, output, other options
exitcode	F6	out	Extended exit codes (how field exited)
timer	F6	in/out	Used to specify time-out duration
cmdflg	Num	in	Controls whether command file input allowed
defpt	Num	in	Specifies default decimal point
maxpt	Num	in	Specifies maximum digits to right of decimal
funmap	Num	in	Controls interpretation of function keys
setdef	String	in	Defines list or set of allowable inputs
infclr	→	in	(Structure or 0) Color specifications
hlpidx	String	in	Various expansion features
maxchrs	Num	in	Maximum number of characters allowed (independent of xmax)
