  80. * (UFD) ON THE APPROPRIATE USER'S DISK. 00084000
  81. * 00085000
  82. * HAVING UPDATED THE USER FILE DIRECTORY, INIT CHECKS THE 00086000
  83. * RETURN CODE THAT HAD BEEN PASSED BACK. IF THE CODE IS ZERO, 00087000
  84. * INIT TYPES A READY MESSAGE AND THE CPU TIME USED BY THE 00088000
  85. * GIVEN COMMAND. IF THE CODE IS POSITIVE, AN ERROR MESSAGE IS 00089000
  86. * TYPED, ALONG WITH THE CPU TIME USED. THE COMMAND WILL HAVE 00090000

  90. * IF THE CODE IS NEGATIVE, INIT CHECKS IF THERE HAD BEEN ANY 00094000
  91. * PROBLEM DETECTED IN LOADMOD, FOR IF THERE HAD THE 00095000
  92. * COMMAND CANNOT BE ASSUMED TO BE A CP COMMAND. OTHERWISE, 00096000
  93. * INIT WILL ISSUE A DIAGNOSE INSTRUCTION TO PRESENT THE 00097000
  94. * COMMAND LINE TO THE CP ENVIRONMENT. IF IN FACT THE 00098000
  95. * COMMAND IS NOT CP'S, INIT WILL TYPE THE MESSAGE "UNKNOWN 00099000
  96. * COMMAND". (AS WOULD BE THE CASE FOR A BAD LOADMOD.) 00100000
  97. * INIT THEN PROCEEDS IN THE MAIN CONTROL LOOP TO CALL CONREAD 00101000
  98. * TO GET THE NEXT COMMAND. WHEN THE COMMAND IS ENTERED, INIT 00102000
  99. * CALLS SETCLK TO INITIALIZE THE CPU TIME FOR THE NEW COMMAND 00103000
  100. * AND THEN PUTS IT IN STANDARD PARAMETER-LIST FORM BY CALLING 00104000
  101. * THE SCAN FUNCTION PROGRAM. AFTER CALLING SCAN, INIT CHECKS 00105000
  102. * TO SEE IF AN EXEC FILETYPE EXISTS WITH A FILENAME OF THE 00106000
  103. * TYPED-IN COMMAND. (FOR EXAMPLE, IF ABC WAS TYPED IN, INIT 00107000
  104. * CHECKS TO SEE IF ABC EXEC EXISTS.) IF SUCH AN EXEC FILE 00108000
  105. * DOES EXIST, INIT ADJUSTS REGISTER 1 TO POINT TO THE SAME 00109000
  106. * COMMAND AS SET UP BY SCAN, BUT PRECEDED BY CL8'EXEC', AND 00110000
  107. * THEN ISSUES AN SVC X'CA' TO CALL THE CORRESPONDING EXEC 00111000
  108. * PROCEDURE ('ABC EXEC' IN THE EXAMPLE). 00112000
  109. * 00113000
  110. * IF NO SUCH EXEC FILE EXISTS FOR THE FIRST WORD TYPED IN, 00114000
  111. * INIT MAKES ONE FURTHER CHECK USING THE CMS'ABBREV' 00115000
  112. * ABBREVIATION-CHECKER. IF, FOR EXAMPLE, THE FIRST WORD TYPED 00116000
  113. * IN HAD BEEN 'FORT', INIT LOOKS UP FORT VIA THE ABBREV 00117000
  114. * ROUTINE FOR AN EQUIVALENT FORM; IF AN EQUIVALENT IS 00118000
  115. * FOUND (FOR EXAMPLE, 'FORTRAN' FOR 'FORT'), INIT LOOKS FOR AN 00119000
  116. * EXEC FILE WITH THE NAME OF THE EQUIVALENT WORD (FOR EXAMPLE, 00120000
  117. * FORTRAN EXEC); IF SUCH A FILE IS FOUND, INIT ADJUSTS R1 AS 00121000
  118. * DESCRIBED ABOVE TO CALL EXEC AND SUBSTITUTES THE EQUIVALENT 00122000
  119. * WORD, FORTRAN, FOR THE FIRST WORD TYPED IN. THUS IF FORT IS 00123000
  120. * A VALID ABBREVIATION FOR FORTRAN AND THE USER HAS AN EXEC 00124000
  121. * FILE CALLED 'FORTRAN EXEC', HE INVOKES THIS WHEN HE MERELY 00125000
  122. * TYPES IN 'FORT' FROM THE TERMINAL. 00126000
  123. * 00127000
  124. * IF NO EXEC FILE IS FOUND EITHER FOR THE ENTERED COMMAND NAME 00128000
  125. * OR FOR ANY EQUIVALENT FOUND BY ABBREV, INIT LEAVES THE 00129000
  126. * TERMINAL COMMAND AS PROCESSED BY SCAN AND THEN ISSUES AN SVC 00130000
  127. * X'CA' TO PASS CONTROL TO INTSVC WHICH, IN TURN, PASSES 00131000
  128. * CONTROL TO THE APPROPRIATE COMMAND PROGRAM. WHEN THE COMMAND 00132000
  129. * TERMINATES EXECUTION, OR IF INTSVC CANNOT EXECUTE IT, THE 00133000
