String Functions

FlexPDE provides minimal support for dynamically constructing text strings.

$integer        (i.e. <dollar> integer)

This function returns a text string representing the integer value integer.  This function may be used in conjunction with the concatenation operator "+" to build boundary or region names.  For example

REPEAT i=1 to 4 do

  START   "LOOP"+$i   (x,y)

<path_info>...

ENDREPEAT

This is equivalent to

START "LOOP1" (x,y) <path_info> ...

START "LOOP2" (x,y) <path_info> ...

START "LOOP3" (x,y) <path_info> ...

START "LOOP4" (x,y) <path_info> ...
