Increase the list of symbol names in classicladder

Hello everyone. I'm organizing my programming in Linuxcnc's classicladder. However, I'm not able to name a symbol name for variable %B3 onwards. It doesn't appear in the list when I press the Symbols button in the Section Display of custom.clp window. I've already tried manually editing the custom.clp file in the Geany program, but it didn't work. Note, in the hal file numBits=100 has already been configured, but I'm still not having success. Attached is what has already been done. Does anyone have any suggestions on how to solve this, so I can name the symbol %B2, %B3., %B4 ... onwards?

loadrt classicladder_rt numBits=100 numPhysInputs=99 numPhysOutputs=98 numS32in=99 numS32out=99 numFloatIn=99 numFloatOut=99 numWords=30

 

I've already managed to find out why I need to change numSymbols=200 to numSymbols=300. But it has the right position, if you put it at the beginning it crashes the system. Thank you, I'll leave this post in case anyone needs help with this. Thank you to everyone in this forum
