Return to command index

multi-functional command

command: FCT <subfunction> <p1> ...<pN>

Some low level commands. Action depends on <subfunction>. Only poor documentation about these commands.


  • <subfunction> parameter type: string
    Valid inputs are:
      sets maximum amplitude to be displayed if AMPLICUT flag is set on a trace. With this flag set the display manager cuts off peaks with larger amplitudes than <p1>.
      • <p1> = maximum amplitude for all traces with AMPLICUT flag set
    • AUTHOR
      prints program info
    • AXIS
      sets axis parameters of axis <p1>
      • <p1> = name of axis (string)
      • <p2> = name of axis item (string, see list below)
      • <p3> = new value of axis item valid axis items: VPOS, LINE_S, LINE_E, TICK_S, TICK_INTV, LAB1VAL, LAB_INTV, LAB1CNT, LABCNT, TICK_LTH, LTICK_LTH, LABSHIFT, LABDIST, STYLE, LABFMT
      changes P or S velocities (read in by FCT READ_VEL) by a constant factor <p2>
      • <p1> = P or S
      • <p2> = multiplication factor
      sets correlation mode
      • <p1> = correlation mode number (integer: 1,2 or 3)
    • LOCAL
      executes command which is machine dependend
      sets location file name (file containing location of various stations)
      • <p1> = name and path of location file
    • MARGIN
      sets margin widths of display (in units of width & height)
      • <p1> = name of margin: L(eft), R(ight), T(op), B(ottom)
      • <p2> = margin width in units of width (L,R) and height (T,B)
    • PATH
      sets directory paths
      • <p1> = directory name (valid directory names: SCRATCH, HELP, INPUTS, COMMAND, GLOBALS, FILTER, ERRORS, CURVES)
      • <p2> = new directory string (string)
      inserts text file as a comment into header of q-file
      • <p1> = comment file
      • <p2> = q-file
    • QDIR
      set file prefix for q-file operations. To be used if header and binary files are on different directories.
      • <p1> = H (for header files) or B (for binary files)
      • <p2> = file prefix
    • QLINES
      add info lines to a q-header file. If a new trace is appended to an existing q-file it may occur that there are not enough info lines in the q-file to hold all the information assigned to the new trace. With this command you can extend the number of info lines pre trace in the q-file by <p2> lines.
      • <p1> = q-file name
      • <p2> = number of info lines to be added on each trace
    • READ_VEL
      reads velocity file (for PS-delay routines)
      • <p1> = name of velocity file (default extension ".VEL")
    • SETPAR
      sets graphics parameters
      • <p1> = channel map
      • <p2> = item to be changed (depends on graphic channel)
      • <p3> = new value of item
      changes style attribute block number <p1>.
      • <p1> = line attribute block number (integer)
      • <p2> = attribute name (string, see list below)
      • <p3> = new value of attribute valid attribute names: CHARSIZE, COLOR, FONT, LINESTYLE, LINEWIDTH, WRMODE (REPLACE, XOR)
      insert station to location file
      • <p1> = station name (string)
      • <p2> = latitude (real)
      • <p3> = longitude (real)
      • <p4> = array code (integer)
      • <p5> = rel. array x-position (real)
      • <p6> = rel. array y-position (real)
      • <p7> = comment (string)
    • TT_TABLE
      set name of travel time table
      • <p1> = name of ASCII travel time table

Deprecated values:

    changes terminator set of command line parser (dangerous command! May confuse beginners, included command procedures won't run anymore!)
    • <p1> = string containing new terminator set (1. char: BLANK; 2. char: qualifier; all others: additional terminators; default is " /;"
    sets hardcopy parameters (will be replaced by SETPAR in future)
    • <p1> = item to be changed (VAX: JOB_QUEUE HC_QUEUE CCPAR CCROT)
    • <p2> = new value of item


fct qdir b opdir:
adds string "opdir:" at the beginning on every file access to a q-binary file.
