TXT.ril
TXT.Replace_in_Line
Search a Text in the TXT.-internal Buffer in a specified Line and replace just the first match with a given other string.
Intention
This command is specific in that it will only replace the first match of P2 in the specified Line with P3.
Also you can specify a starting Position in P4.
If you want to replace all occurrences in a Line, you can get the Line-Position using TXT.glp and then use TXT.rep.
Or just call TXT.ril multiple TImes until the TOS returns "0".
The command will leave a "0" or a "1" on the TOS, depending if there was a replace or not.

' This example shows all features of TXT.ril
' We are running in 2 times so its clear that due to the Equalcase-Replace,
' also the "EE" will be treated as "ee" and replaced.
TXT.ril|e|EE|520
TXT.ril|e|EE|520
' You can also see that the replace starts a Position 520, as specified.
' So the start of the text is unchanged.
