read from a txt file multiple entries and assign to variables

Im learning C coding and have successfully used the code below to read from a txt file the single entry HSI0 or HSI1 and assign the one or zero to the variable CommandDirection.

Code:

LE * pFile;  
    pFile = fopen ("R:\\SierraChart\\Commands.txt","r");
    if (pFile!=NULL) {
        // obtain file size:
        long lSize;  char filetxt[40]=""; char out[1];
        fseek (pFile , 0 , SEEK_END);
        lSize = ftell (pFile);
        rewind (pFile);
        fread (filetxt,1,lSize,pFile);
        fclose (pFile);
        
        SCString InputString(filetxt), HSISymbol("HSI"); 
        
        if(InputString.CompareNoCase(HSISymbol,3)==0) {out[0]=filetxt[3]; CommandDirection=atoi(out);}
    }

I'm trying to expand that one entry to multiple entries, in order to assign to multiple variables.

The code below doesn't work, but perhaps will give an idea what I'm trying to do.

new format in txt file entries:
HSI1
TESTA2
TESTB3

proposed enhancement:

Code:

SCString InputString(filetxt), HSISymbol("HSI");
SCString InputString2(filetxt), testSymbolA("TESTA");
SCString InputString3(filetxt), testSymbolB("TESTB");

if(InputString.CompareNoCase(HSISymbol,3)==0) {out[0]=filetxt[3]; CommandDirection=atoi(out);}
if(InputString2.CompareNoCase(testSymbolA,3)==0) {out[0]=filetxt[3]; CommandDirection2=atoi(out);}
if(InputString3.CompareNoCase(testSymbolB,3)==0) {out[0]=filetxt[3]; CommandDirection3=atoi(out);}

so result would be
CommandDirection=1
CommandDirection2=2
CommandDirection3=3

I am missing some parsing and assignment magic, please help.
There may be some Sierra Chart coding ACSIL specific functions in the above code, but I'm not positive.

Well char out[1] isn't large enough to hold your string, there is no room for a \0.

So perhaps your atoi() is processing garbage.

OK thanks I found an solution here
