cmd_ifthen |
Function (ROM Call 0x355) |
Executes TI-Basic 'If'...'Then' command.
cmd_ifthen is an internal subroutine used by TI-Basic interpreter for
executing 'If'...'EndIf' and 'If'...'Else'...'EndIf' blocks (searches for a matching
'Else', 'ElseIf' or 'EndIf' instruction and transfers the control there if the
condition is not true).
As this function depends heavily on some system state variables of the
TI-Basic intepreter which are not set correctly while executing an ASM
program, it is extremely unlikely that this function may be used inside a C
program for anything useful.
Note: See the if
and
else
keywords to learn how to
implement conditional execution in the C language.
Uses: next_expression_index, push_internal_simplify, top_estack, index_after_match_endtag, NG_control, ROM Call 0x5C8
